Question

ABCD is an isoceles Trapezium. Side AB || side DC.E is a point on side DC such that ∆BEC is an equilateral triangle. What is the measure of ∠A *

Answer 1

            In △ADE and △BCF

                ∠A=∠B (Base angle is same in Isosceles)

                ∠CFB=∠DEA=90∘

                   AD=BC

             △ADE≡△BCF (by ASA)

Answer 2
