In a quadrilateral ABCD, angleA + angleD =90°.prove that AC^2 +BD^2=A

1.	In a quadrilateral ABCD, angleA + angleD =90°.prove that AC^2 +BD^2=AD^2 + BC^2
Answer» Q.In a quadrilateral ΔBCD, ∠A+ ∠D = 90°. Prove that AC2\xa0+ BD2\xa0= AD2\xa0+ BC2.\xa0Given Quadrilateral ΔBCD, in which ∠A+ ∠D = 90°To prove\xa0AC2\xa0+ BD2\xa0= AD2\xa0+ BC2Construct Produce AB and CD to meet at E. \xa0 ^ iska matlab to the power h Iska matlab AC ki power 2 hota h Ismain (^) this means?? Plz post clearly this one...
