A rhombus is a quadrilateral that has diagonals that bisect each other. Anything you can say about the angles and segments of a rhombus can be said about the angles and segments of the figure created by these mutual perpendicular bisectors.
A rhombus has 4 equal-length sides. Opposite sides are parallel, and opposite angles are congruent. Adjacent angles are supplementary. Each diagonal bisects the angles at either end.
