Diagonals of parallelogram ABCD bisect at O, so OA = OC and OB = OD. Since DP = BQ, subtracting gives OP = OQ. With diagonals AC and PQ bisecting each other, APCQ is a parallelogram.

Class 9 Quadrilaterals Solutions – Ganita Manjari Part II Chapter 12
Let O be the intersection point of the diagonals AC and BD of parallelogram ABCD. Since the diagonals of a parallelogram bisect each other, OA = OC and OB = OD. Given that DP = BQ, we have OP = OD – DP = OB – BQ = OQ. The diagonals AC and PQ of quadrilateral APCQ bisect each other at O, which proves APCQ is a parallelogram.
