If P and Q are any two points lying respectively on the sides DC and AD of a parallelogram ABCD then show that ar(△APB)=ar(△BQC).

If P and Q are any two points lying respectively on the sides DC and A

1.	If P and Q are any two points lying respectively on the sides DC and AD of a parallelogram ABCD then show that ar(△APB)=ar(△BQC).
Answer» If P and Q are any two points lying respectively on the sides DC and AD of a parallelogram ABCD then show that $a r (△ A P B) = a r (△ B Q C)$ .
