Explanation Given: ABCD is trapezoid such that A D ¯ ∥ B C ¯ and A D > B C and if A B = C D Approach: H-L Congruency rule: Two right angled triangles re congruent if one side and the hypotenuse of the one are respectively equal to the corresponding side and the hypotenuse of the other. Definition of trapezoid: A trapezoid is a four sided flat shape with straight sides that has a pair of opposite sides parallel. Calculation: Let us draw perpendicular from B and C on AD as BE & CF.
