A quadragon is a four-sided polygon. There are three words in English that mean the same thing: quadrangle, quadragon, and quadrilateral. Quadragon literally means four angles as does quadrangle. Quadrilateral literally means four sides. Some quadragons have special properties and special names: parallelograms, rectangles, rhombuses, squares, trapezoids, and kites, for example.
