Web27. A triangle is circumscribed by a circle where the longest side of the tria ngle is a diameter of the circle. What can be said about the triangle? (a) It is an isosceles triangle. (b) It is an obtuse triangle. (c) It is a scalene triangle. (d) … WebAn obtuse triangle has only one angle greater than 90° since the sum of the angles in any triangle is 180°. If one of the angles is greater than 90°, then the sum of the other two angles must be less than 90°, so the other two angles must both be acute angles. For DEF above, ∠D + ∠F = 60° < 90°, so ∠D and ∠F are acute angles.
How to Determine Right, Acute, Obtuse, or No Triangle
WebNov 2, 2016 · Properties of Obtuse Triangles The longest side of an obtuse triangle is the one opposite the obtuse angle vertex. An obtuse triangle … The area of an obtuse triangle can also be found by using Heron's formula.Consider the triangle ΔABC with the length of the sides a, b, and c. Heron's formula to find the area of an obtuse triangle is: √s(s−a)(s−b)(s−c)s(s−a)(s−b)(s−c), where, (a + b + c) is the perimeter of the triangle and S is the semi-perimeter which is … See more The perimeter of an obtuse triangle is the sum of the measures of all its sides. Hence, the formula for the perimeter of an obtuse-angled triangle … See more To find the area of an obtuse triangle, a perpendicular line is constructed outside of the triangle where the height is obtained.

WebA corollary to the theorem categorizes triangles in to acute, right, or obtuse. In a triangle with side lengths , , and where is the length of the longest side, if then the triangle is acute, and if then the triangle is obtuse. Example 2: … WebApr 13, 2024 · How to Measure an Obtuse Angle. To measure an obtuse angle, you can use a protractor. Align the base of the protractor with one side of the angle and then read the measurement from the degree scale. Alternatively, if you know the values of the other angles in a triangle or other shape, you can use those values to calculate the missing angle. WebAs illustrated below and by other available solutions, after applying the Converse of the Pythagorean Theorem, this application will return a determination as to whether a triangle with the given side lengths is a Right Triangle.And if the given side lengths form a Right Triangle and they are all positive integers, the application will note that the given side … flower petal earrings handmade
