can a triangle have two obtuse angles

The side that does not have the same length is called the base of the triangle. No, they can never have 2 obtuse angles. The angle sum of triangle is 180. Obtuse angles are angles between 90 and 180 degrees. If you add two of t... Because all the angles in a triangle add up to 180°, the other two angles have to be acute (less than 90°). 2) obtuse angle of a triangle is between 90 and 180. An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles. Answer (1 of 15): For every triangle the sum of its 3 inner angles equals 180 degrees, and each angle is greater than 0 degrees. Since 3 out of 2 people … Obtuse Triangle A triangle can never have only one acute angle. Soumitraghosh017 Soumitraghosh017 21.02.2021 Math Primary School answered 11. Answer by Fombitz (32379) ( Show Source ): You can put this solution on YOUR website! Therefore there is no "largest" or "smallest" in this case. The sum of the two angles in a triangle, excluding the obtuse angle, is less than 90 degrees. Answer:hiibuddy here is your answerStep-by-step explanation:Triangle cannot have more than one obtuse angle because there are 3 side and if you add three sides … abhilika29 abhilika29 17.03.2020 Math Secondary School answered Can a triangle have three obtuse angles 2 An obtuse triangle can have two obtuse angles? - Answers two angles opposite to the legs are equal in length; the isosceles triangle can be acute, right or obtuse, but it depends only on the vertex angle (base angles are always acute) The equilateral triangle is a special case of a isosceles triangle. An obtuse angle is one whose value is greater than 90° but less than 180°. We know that sum of the three angles of a triangle is 180 ∘ and if there are two obtuse angle, then the third angle will be negative which is not possible. In an acute triangle all three angles are acute (less than 90 degrees). Therefore, a triangle can never have more than one obtuse angle. When an angle of a triangle is 90 degrees, the triangle cannot have an obtuse angle. The other two must each be less than 90 degrees (90 deg + 89 deg + 1 deg = 180 deg). For studying the obtuse angled triangle, we have to measure the remaining angles and it can be done by a protractor. If two angles (A,B) are greater than 90, then their sum would be greater than 180. So, triangle can not have two right angle. We can use the Cosine Law three times to get the three angles. As if the sum of the square of the two shortest sides … Similarly, a triangle can never be a right angle and an obtuse angle at the same time as per the angle sum property of a triangle. Step-by-step explanation: A triangle can't have 2 obtuse angles. a triangle Can An obtuse angle occupies ¼ and ½ of a circle if divided into four parts. If a triangle has 1 acute angle, the other angles will be either right angles or obtuse angles which is not possible as the sum of interior angles of a triangle is always 180°. An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). can We can find the area of an obtuse triangle by creating an altitude line. Basic facts : 1) triangle is a shape having three angle made by three lines and sum of all three angles is 180. So, using the above analysis, we can conclude that the statement is possible. An obtuse triangle has one obtuse angle. No, because if the triangle have two obtuse angles i.e., more than 90° angle, then the sum of all three angles of a triangle will not be equal to 180°. A triangle cannot have two right angles. The sum of all three internal angles of a triangle is always 180 degrees. If two angles of a traingle measured 90 degrees each, the third angle would have to measure 0 degrees. If the third angle was 0 degrees, it is not a triangle anymore. An internal angle of the triangle is obtuse, that is, it has more than 90 degrees. (d) The difference between the lengths of any two sides of a triangle is greater than the length of the third side. (a) A triangle can have all the three angles equal to 60°. Not in Euclidean geometry. Euclidean geometry [ https://en.wikipedia.org/wiki/Euclidean_geometry ] is the “standard” type of geometry that you lear... Triangles can be classified as 6 different types, based on their side length and angles. So option A is false. Angles on opposite equal sides are also equal and acute. No. Since a triangle’s angles must sum to 180° in Euclidean geometry, no Euclidean triangle can have more than one obtuse angle. (ii) In a triangle, two obtuse angle cannot be possible. Can scalene triangle have a right angle? A quadrilateral cannot have 3 obtuse angles, where an obtuse angle is an angle that has a measure that is greater than 90°. Since the sum of all angles of a triangle is 180 ∘. Can a triangle have(i) two right angles? Example 1: If a triangle has two obtuse angles then sum of angles of triangle exceeds 180 ∘ which is not possible. (ii) two obtuse angles? That would be zero.. Obtuse means more than 90 degrees. Obtude = Greater than 90 degrees Triangles need 3 angles to add up to 180. If two of those add up to 180, the third must be 0, which is impossible. But by definition, obtuse angles are greater than 90 degrees, so the sum of 2 obtuse angles is greater than 180 degrees. Answer:No. Answer: No. The correct option is A. Solution. Does obtuse triangle have any angles congruent? Findings: a triangle can have maximum of one obtuse angle. ( 1). Triangles can be classified on the basis of their angles as acute, obtuse and right triangles. ∴ (i), (iii) are wrong because the sum of all three angles should be 180 ∘. Only (ii) If two angles of the triangle are obtuse in a triangle, then the sum of interior angle of the triangle would become more than 180 ∘ And also, all the angles in the triangle cannnot be more than 60 ∘ because of the same reason. It’s impossible for a triangle to have more than one obtuse angle. In one angle of a triangle is obtuse, then it cannot be a right angled triangle. Since a triangle's angles must sum to 180° in Euclidean geometry, no Euclidean triangle can have more than one obtuse angle. No. A scalene triangle can have a right angle, or an angle with measure 90°, but not all scalene triangles have a right angle. An isosceles triangle has two congruent angles. Show Answer Since ACD is a right triangle, we can find it’s area with the equation A = ½ base × height. Therefore, an obtuse-angled triangle can never have a right angle; and vice versa. sin x = ½, for example, we would have. So, a right triangle will have angles of 90, 45 and 45 degrees. An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles. please Justify your answer. A triangle can never have only one acute angle. If a triangle has 1 acute angle, the other angles will be either right angles or obtuse angles which is not possible as the sum of interior angles of a triangle is always 180°. So, every triangle needs to have at least 2 acute angles. ∠ABC, ∠ACB and ∠BAC are all acute angles. An equilateral triangle has all sides equal in length and all interior angles equal. Which of the following statements is true? Then, we can determine if a triangle is acute, right, or obtuse by using the converse Pythagorean theorem. Obtuse angled triangles in real life: Acute and obtuse … An acute triangle has all of its angles as acute. If a triangle has two acute angles and a single obtuse angle, the triangle is called an Obtuse Triangle. eddibear3a and 3 more users found this answer helpful. An obtuse triangle can also be called an obtuse-angled triangle. If a triangle has two right angles then the third angle becomes zero which is not possible. A tria ngle can obviously have two acute angles for example equilateral triangle. Because if there are two obtuse angle in a triangle they would sum up to exceed 180 degree. Dwfinitely not. An obtuse angle is one that is greater than 90 degrees. Two of these would be more than 180 degrees, so it would be impossible to f... ⇒ If triangle have three angle, then sum of three interior angle of a triangle will be grater than 1 8 0 o and it will not satisfy property of triangle. To meet the angle sum property of the triangle, an obtuse triangle can have just one obtuse angle. No. Obtuse Triangle Definition An obtuse triangle is one that has an angle greater than 90°. So, every triangle needs to have at least 2 acute angles. And we reach the conclusion that a triangle cannot have two obtuse angles. The angle Q P R is known and it is 105 °. Obtuse triangles have one obtuse angle (angle which is greater than 90°). (iii) In a triangle, two acture angles are possible as sum of three angles of a triangle is 180 ∘. If two of the angles are right angles, the two sides would be parallel lines. A triangle can have 3 acute angles, but only one obtuse angle. All the angles of a triangle can be less than All the angles of a triangle can be greater than All the angles of a triangle can be equal to A triangle can have two obtuse angles. So option D is correct. An obtuse triangle is one that has an angle greater than 90°. In the following example, we will see how this ambiguity could arise. Not in the Euclidean plane, but a spherical triangle can have two or even three obtuse angles. see Spherical trigonometry - Wikipedia [ https://en.... … Can scalene triangle have a right angle? Because all the angles in a triangle add up to 180°, the other two angles have to be acute (less than 90°). Never ,a triangle cannot have two obtuse angle because the measure of one obtuse angle is greater than 90 degree.,as a result the formed sum/total measure of two obtuse angles will be more than 180 degree , which can not be considered as the measure of triangle.because the total measure of triangle is 180° and it contradict that . It is measured that. Two properties that hold true for all rectangles but not for all rhombuses All angles must be right angles & All diagonals are the same length. We can also determine the area of the larger triangle ABD using this equation. Answer: If a triangle does not have a specific mention of a right angle. An obtuse angle occupies ¼ and ½ of a circle if divided into four parts. When two angles are connected with one common arm and have one common vertex and also the non-common arms are either side of the common arm, then they are called adjacent angles. It is possible to have a obtuse isosceles triangle – a triangle with an obtuse angle and two equal sides. In a concave quadrilateral, one interior angle is bigger than 180°, and … An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles. Thus, we can conclude that if one of the angles of a triangle is obtuse, then the other two angles of a triangle must be acute angles. Since the three angles in a triangle add up to 180°, every triangle needs to have at least 2 acute angles (since 2×90=180 and a triangle has 3 angles). Can a quadrilateral have 1 reflex angles? 16. The sum of the 3 angles of a triangle equals 180. To meet the angle sum property of the triangle, an obtuse triangle can have just one obtuse angle. Any triangle can have at most only one obtuse angle. Answer (1 of 4): The expression for the sum of interior angles in any polygon is (N - 2) \times 180 Where N is the number of sides. Take for instance, the angles in the triangle are 100, 40 and 40. Since a triangle’s angles must sum to 180° in Euclidean geometry, no Euclidean triangle can have more than one obtuse angle. Some right triangles can be a scalene triangle when the other two angles or the legs are not congruent. Also, on other hand, no angle of a triangle can be 0 ∘ so we can not have a triangle with two right angles. The sum of angles in a triangle must be 180° and no triangle can have more than one obtuse angle. A right triangle can be an isosceles triangle if the OTHER two angles are equal. The side opposite the obtuse angle in the triangle is the longest. Question 180206: 1. No it can’t cause the angles would then equal to more than 180 degrees. Since the three angles in a triangle add up to 180°, every triangle needs to have at least 2 acute angles (since 2×90=180 and a triangle has 3 angles). We can observe that the two angles are acute angles. Therefore, a triangle can have two acute angles as the sum of those two angles becomes less than 180 ∘.
