Rectangle-rhombus duality. The dual polygon of a rectangle is a rhombus, as shown in the table below. [10] Rectangle Rhombus All angles are equal. All sides are equal.
Dorman Luke construction, showing a rhombus face being dual to a rectangle vertex figure. Regular polygons are self-dual. The dual of an isogonal (vertex-transitive) polygon is an isotoxal (edge-transitive) polygon. For example, the (isogonal) rectangle and (isotoxal) rhombus are duals.
Rectangle – A parallelogram with four angles of equal size (right angles).; Rhombus – A parallelogram with four sides of equal length. Any parallelogram that is neither a rectangle nor a rhombus was traditionally called a rhomboid but this term is not used in modern mathematics.

These include as special cases the rhombus and the rectangle respectively, and the square, which is a special case of both. [1] The self-crossing quadrilaterals include another class of symmetric quadrilaterals, the antiparallelograms. [16]
