A polygon of four sides where every angle is a right angle (90°)[1].


As a result of this defintion:

  • Each pair of opposite sides is of equal length.
  • Opposite sides are parallel
  • Diagonal are equal
  • Adjacent sides are perpendicular

However, the adjacent sides do not need to be of equal length.

A specific case of a rectangle is is the square, which is also a rhombus.

Notes

  1. ↑ There are many definitions of rectangle, but it seems sensible to use one which ais based on angle properites reather than length or papallesim properties. Definition adapted from http://www.mathsisfun.com/definitions/rectangle.html
