Points P and Q have been taken on opposite sides AB and CD respectively of a parallelogram ABCD such that AP =CQ. Then, which of the following option is correct?
AC and PQ bisect each other
In AOP and COQ, we have,
AP = CQ [given]
∠1=∠2 [∵ alternate interior ∠s]
∠3=∠4 [vertically opp. ∠s]
∴AOP≅COQ [by AAS congruence rule]
∴ OA = OC and OP = OQ [CPCT]
Hence, AC and PQ bisect each other.
