WebDec 9, 2024 · Example 1: Find ∠BAC of an isosceles triangle in which AB = AC and ∠B = 1/3 of right angle. Example 2: In isosceles triangle DEF, DE = EF and ∠E = 70° then find other two angles. Example 3: ∆ABC and ∆DBC are two isosceles triangles on the same base BC and vertices A and D are on the same side of BC (see fig.). WebJan 11, 2024 · 1. The area of the triangle is x ⋅ x ⋅ sin ( A) 2 it is also x ⋅ 1 ⋅ sin ( 2 A) 2. Therefore, x sin ( A) = sin ( 2 A). Since sin ( 2 A) = 2 sin ( A) cos ( A), we get that x = 2 … WebThe formula to calculate the area of an isosceles triangle is given by: The area of an isosceles triangle A = ½ × b × h Square units where b is the base and h is the triangle’s height.
