Consider the DIAGRAM given in the question.

As we know, the DIAGONALS of a parallelogram bisect each other.

Therefore,

⇒AC and BD bisect each other at point O.

Thus,⇒OA=OC and OB=OD

Now, consider POINTS P and Q.

⇒BP=PQ=DQ ---- (1)

(1)Now, since OB=OD,

soPB+OP=OQ+DQFrom equation (1),

DQ+OP=OQ+DQ∴OP=OQ

Thus, AC and PQ bisects each other.

Thus, APCQ is a parallelogram, because both the diagonals bisect each other. Also, since, CQ and AP are the opposite sides of the parallelogram APCQ, they are parallel to each other.
