AI overview
A rhombus is a four-sided shape where all four sides are equal in length and opposite sides are parallel to each other. It's a useful geometric form that includes the square as a special case and serves as a building block for understanding other shapes like kites and parallelograms.

In geometry, a rhombus (: rhombi or rhombuses) is an equilateral quadrilateral, a quadrilateral whose four sides all have the same length. Other names for rhombus include diamond, lozenge, and calisson.
