Click to know more about … WebAll the angles of the triangle are less than 90°. Therefore, the triangle is acute. 3. In an isosceles triangle, ABC, ∠A = 100° and ∠B = ∠C. Find the measure of ∠C. Solution: Following the angle sum property of a triangle, we get ∠A + ∠B + ∠C = 180° So, ∠B + ∠C = 180° – 100° = 80° Since ∠B = ∠C, measure of ∠C = 80° ÷ 2 = 40° Practice Problems 1
