Quadrilaterals and Their Properties Quadrilaterals have 4 rigid sides. Trapezium Kite  One pair of opposite sides parallel  2 pairs adjacent sides equal  1 pair opposite angles equal Parallelogram (angles between unequal sides)  The diagonal between equal sides  Both pairs opposite sides equal in length bisects the other diagonal  Both pairs opposite angles equal  The diagonal between equal sides  Both diagonals bisect each other bisects the interior angles  Both pairs of opposite sides parallel  The diagonals intersect at 90° Rectangle Square  All the properties of a parallelogram +  All 4 angles equal to 90°  Diagonals equal in length  All the properties of a parallelogram +  All 4 angles equal to 90°  Diagonals equal in length Rhombus  Diagonals bisect each other at 90°  Diagonals bisect both pairs of interior opposite angles (i.e. all 45°)  All the properties of a parallelogram +  All 4 sides equal  All 4 sides equal  Diagonals bisect each other at 90°  Diagonals bisect both pairs of opposite angles
