A Quadrilateral is a polygon with four sides…

The Square…

All four angles are equal. The diagonals of a square bisect each other. The diagonals of a square bisect it’s angles. The diagonals of a square are perpendicular. Opposite sides of a square are parallel and equal

Opposite sides of the rhombus have equal measure The two diagonals of a rhombus are perpendicular. Every rhombus is a kite.

Opposite sides of a parallelogram are equal in length. Opposite angles of a parallelogram are equal in size. Opposite sides of a parallelogram never intersect. The diagonals never bisect each other

It is convex and cyclic All angles are 90 degrees Opposite sides are parallel The two diagonals bisect each other

All vertices lie in a single circle Opposite angles are supplementary Exterior angle is equal to opposite interior.
