Two unequal circles intersect at P & Q. PA is a tangent to the larger circle and a chord of the smaller one, while QB is a tangent to the smaller circle and a chord of the larger one. Prove that BP is parallel to AQ.

I've gotten the diagram but I don't know how to prove it. I know all my circle properties, but I can't see through this for some reason!

It would be greatly appreciated if someone could help me solve this.

Thanks
