WebIn a trapezium ABCD, if AB CD, then prove that AC²+BC²=BC²+AD²+2AB*CD? I previously showed in my answer to the original question below that for an isosceles trapezium, AC^2 … WebSolution Given, quadrilateral ABCD, in which ∠A+∠D= 90∘ To prove : AC2+BD2 = AD2+BC2 Construction : Produce AB and CD to meet at E. Also, join AC and BD. Proof : In ΔAED, ∠A+∠D= 90∘ [given] ∴ ∠E= 180∘−(∠A+∠D) = 90∘ [because sum of all angles in a triangle= 180∘] Then, by using Pythagoras theorem, AD2 = AE2+DE2 ..(i) I n ΔBEC,
