TextParallelogram and Its DefinitionOpposite Sides of Parallelogram are Equal

In Fig.8.1, it is given that BDEF and FDCE are parallelograms. Can you say that BD = CD? Why or why not?

In Fig. 8.7, P is the mid-point of side BC of a parallelogram ABCD such that ∠BAP = ∠DAP. Prove that AD = 2CD.

In a parallelogram ABCD, AB = 10 cm and AD = 6 cm. The bisector of ∠A meets DC in E. AE and BC produced meet at F. Find the length of CF.

In Fig. 9.4, the area of parallelogram ABCD is :

In Fig. 9.5, if parallelogram ABCD and rectangle ABEF are of equal area, then :

Two parallelograms are on equal bases and between the same parallels. The ratio of their areas is
