This document describes the properties of rectangles, rhombuses, and squares. Rectangles have equal angles but not necessarily equal sides, while rhombuses have equal sides but diagonals that bisect opposite angles and are perpendicular. Squares are both equilateral and equiangular, with equal diagonals that bisect opposite angles and are perpendicular.
