Rectangle

Revision as of 11:24, 17 July 2006 by JBL (talk | contribs)

A rectangle is a quadrilateral in which all angles are right angles. Every rectangle is a parallelogram and so has all the properties of a parallelogram. In addition, rectangles have congruent diagonals.

Squares are the only rectangles which are also rhombuses.
