Also known as antidipyramid, deltohedron, antibipyramid

In geometry, an trapezohedron, -trapezohedron, -antidipyramid, -antibipyramid, -deltohedron, or -antitegum, is the dual polyhedron of an antiprism. The faces of an are congruent and symmetrically staggered; they are called twisted kites. With a higher symmetry, its faces are kites (sometimes also called trapezoids, or deltoids). They are topologically related to the scalenohedra, which are half-symmetry variants with irregular trigons.
