Recently, I bought a book and found a strange question :(adsbygoogle = window.adsbygoogle || []).push({});

In the given figure, PQRS is a quadrilateral. PO and QO are bisectors of angle P and angle Q respectively, then prove that angle QOP = 1/2 (angle R + angle S)

I made several attempts to get the solution but failed. I guess, we need to prove that PQRS is a parallelogram.
