A polygon of four sides where every angle is a right angle (90°)[1].
As a result of this definition:
- Each pair of opposite sides is of equal length.
- Opposite sides are parallel

However, the adjacent sides do not need to be of equal length.
A special case of a rectangle is is the square, which is also a rhombus.
