# Rhombus

Rhombus is a type of quadrilateral which has all four sides equal. It has opposite sides parallel. Rhombus is also known as equilateral quadrilateral. An image demonstrating rhombus is given below:

It is also named as diamond. A square is a kind of rhombus. It is a rhombus with all the interior angles measuring $90^{\circ}$.

## Properties of a Rhombus

The important properties possessed by a rhombus are as follows:
• All sides are equal.
• Opposite angles are equal.
• It has 4 sides, 4 vertices, 4 internal angles and 2 diagonals.
• Both diagonals of rhombus bisect each other.
• Diagonals also intersect each other at right angles.
• The sum of any two adjacent angles of a rhombus is $180^{\circ}$.
• Every rhombus is a parallelogram, but not each parallelogram is a rhombus.
• A rhombus has symmetry along the diagonals.

## Perimeter of a Rhombus

Area of a rhombus can be calculated if the length of both diagonals is known. The formula of area of rhombus whose diagonals are $d_{1}$ and $d_{2}$, is given by:
Area = $\frac{1}{2}$ x product of diagonals = $\frac{1}{2}$$\ d_{1}\ d_{2}$
