A rhombus is a geometric figure that lies in a plane. It is defined as a quadrilateral all of whose sides are congruent. It is a special type of parallelogram, and its properties (aside from those properties of parallelograms) include:
- Its diagonals divide the figure into 4 congruent triangles.
- Its diagonals are perpendicular.
- If all of a rhombus' angles are right angles, then the rhombus is a square.
