## Define Parallelogram

** Example 2: In the following diagram of Quadrilateral PQRS **

PQ is parallel to SR

PS is parallel to QR

PQ = SR = 5 cm

PS = QR = 3 cm

Hence, we can say Quadrilateral PQRS is a parallelogram.

** Definition of Parallelogram : A parallelogram is a quadrilateral in which opposite sides are equal and parallel to each other. **

**Example 1: In the following diagram of Quadrilateral ABCD **

AB is parallel to DC

AD is parallel to BC

AB = DC = 7 cm

AD = BC = 11 cm

Hence, we can say Quadrilateral ABCD is a parallelogram.

PQ is parallel to SR

PS is parallel to QR

PQ = SR = 5 cm

PS = QR = 3 cm

Hence, we can say Quadrilateral PQRS is a parallelogram.
