Diagonals of a parallelogram bisect each other. Given : □PQRS is a parallelogram. Diagonals PR and QS intersect in point O. TO prove : segPO≅segRO, segSO≅segQO
Open in App
Solution
PQRS is a parallelogram where PR and QS are diagonals intersect at point O
In △POS and △ROQ
⇒∠SPO=∠QRO [ Alternate angles between parallel lines are equal ]
⇒∠PSO=∠RQO[ Alternate angles between parallel lines are equal ]
