## Types of Quadrilaterals

- Rectangle
- Square
- Rhombus
- Parallelogram
- Trapezoid/Trapezium
- Kite

### Rectangle

A rectangle is a quadrilateral where every angle is right
angle (90ā°).
It can also be said an **equiangular** quadrilateral as equiangular means that all the angles are equal.

### Square

A square is said to be a regular quadrilateral which means that all the four sides of square are equal and all the angles are also equal that is right angle (90ā°).

### Rhombus

A rhombus is a quadrilateral in which length of all the sides is equal. It is also known as equilateral quadrilateral since equilateral means that all the sides are of equal length. A rhombus looks like a diamond.

### Parallelogram

A parallelogram is a quadrilateral in which opposite sides are parallel and of same length.

### Trapezoid

It is also known as trapezium. It is a quadrilateral shape which has a pair of parallel sides.

### Kite

It is a flat quadrilateral shape which has straight sides. A kite has 2 pairs of adjacent sides with equal length.
