## Definition

**Rhombus** is a two dimensional (2D) geometric shape. It is a quadrilateral and its basic properties are as below:

- All sides are equal.
- Opposite sides are parallel and opposite angles are equal.
- None of the angles is 90 degree.

## Formula

** Area: **of a Rhombus is claculated by the formula:

**(Diagonal 1 * Diagonal 2) / 2 = pq/2**

** Perimeter: **is calculated by the formula:

**4* Side = 4a**

** Relation between side and diagonals: **:

**4 * Side ² = Diagonal1 ² * Diagonal2 ²**
