Quadrilateral & types of quadrilateral

The quadrilateral is a two-dimensional closed shape which is made from four line segments.

- Quadrilateral has four sides.
- It has four vertices.
- Quadrilateral has four interior angles.
- It has two diagonals.
- A quadrilateral is also known as a polygon.
- Sum of all the angles in a quadrilateral is 360Âº.

There are various Quadrilaterals which we use in our daily life. Let's discuss the classifications of Quadrilateral, its properties, etc.

## Square

Square is a quadrilateral which has all sides of equal length & all angles are 90Âº.

- Square has four vertices.
- All interior angles of a square are 90Âº.
- Square has two diagonals of equal length.
- Diagonals of a square equally intersect to each other.
- Opposite sides of the square are parallel & equal in length.

## Rectangle

The rectangle is a quadrilateral whose opposite sides are equal in length.

- Opposite sides of the rectangle are parallel & equal in length.
- Rectangle has all angles are 90Âº.
- Length of it's both diagonals are equal.

## Rhombus

Rhombus is a quadrilateral whose all sides are equal in length but their diagonals are different in length & their opposite angles are equal.

- Length of diagonals of a rhombus is not the same.
- Both diagonals of a rhombus intersect at 90Âº to each other.

## Parallelogram

A parallelogram is also a quadrilateral whose opposite sides are parallel & equal to each other & opposite angles are equal.

- In parallelogram opposite side are parallel to each other.
- Sum of its adjacent angles is 180Âº.

## Kite

Kite is a quadrilateral whose adjacent sides are equal in length.

- We may find the area of a kite by dividing it into two equal triangles.
- Kite has two diagonals.

## Trapezium

A trapezium is a quadrilateral whose two opposite sides are parallel to each other. While its other two sides are non-parallel.
