Parallelogram is a quadrilateral which has both pairs of opposite sides parallel and equal in length. The opposite or facing sides of a parallelogram are of equal length, and the opposite angles of a parallelogram are equal. It is similar to other quadrilaterals like the square and the rhombus.

**Properties of a Parallelogram:**
- Any side can be considered as a base for calculating the area

- The altitude or height of the parallelogram is perpendicular from the base to the opposite side

- The area of a parallelogram can be found by multiplying a base by the corresponding altitude

- The perimeter of a parallelogram is the distance around it or the sum of its sides

In the figure, angles "a" are the same, and angles "b" are the same

The Area and Perimeter of the Parallelogram can be calculated by using the following formula:

Area:

*A = bh*
Perimeter:

*P = 2a + 2b*
