Example: A chess board.

There are different types of quadrilaterals such as parallelogram, rectangle square, rhombus trapezoid and kite.

A) Parallelogram: It is quadrilateral with two pairs of parallel sides and opposite angles are equal.

B) Rectangle : It is quadrilateral with all the 4 angles of equal measure, each of them is .

C) Rhombus: It is a quadrilateral with all the four sides having equal lengths and the opposite sides are parallel.

D) Trapezoid: It is a quadrilateral with one and only one pair of parallel sides.

Area of trapezoid = $\dfrac{{\left( {a + b} \right)}}{2} \times h$

a = long base

b = short base

h = altitude

Some of the properties are as follows:

- Opposite angles are equal.

- Opposite sides are equal and parallel.

- Diagonals bisect each other.

- Sum of any two adjacent angles is $180^\circ$
