Question

in the given figure PQRS is a llm, PO and OQ are the bisector of angle P and Q prove that angle QOP is 90 degree.​

Answer 1

Answer:

solution in Apoq. poq +1/2 p + 1/2 + q =180 (angle sum property of triangle) poq. =180-(1/2p+1/2q) now =180-1/2(p+q) = 180-1/2(360-(str)} =180. -1/2. *360 +1/2(str) =180-180 +1/2(s+r) =0+1/2(s+r) now. poq=1/2(s+r) hence proved ·
