WebThe area of a scalene triangle can be calculated using Heron's formula, Area of triangle = √ [s (s−a) (s−b) (s−c)], when all the three side lengths are given. Here, a, b and c are the 3 different sides of the scalene triangle, … WebWhen two sides of a triangle are equal, the angles at the ends of those sides will also be equal. We are given the angle 64º. 64º. As this is an isosceles triangle (two equal length sides and two equal angles), the other angle at the bottom will also be 64º 64º. Show step. Subtract 128º 128º from 180º 180º. Show step.
WebAn obtuse triangle is a triangle in which one of the interior angles is greater than 90°. It has one of its vertex angles as obtuse and other angles as acute angles i.e. when one angle measures more than 90°, the sum … WebDraw a 30-60-90 triangle and its reflection about the leg opposite the 60° angle. These two 30-60-90 triangles together form a larger triangle. This larger triangle has three 60° angles and is therefore equilateral! The hypotenuse of either one of the 30-60-90 triangles is one of the sides of the equilateral triangle.
