A truncated triangular prism is a triangular prism constructed by truncating its part at an oblique angle. As a result, the two bases are not parallel and every height has a different edge length. If the edges connecting bases are perpendicular to one of its bases, the prism is called a truncated right triangular prism.
A twisted prism is a nonconvex polyhedron constructed from a uniform n-prism with each side face bisected on the square diagonal, by twisting the top, usually by π / n radians ( 180 / n degrees) in the same direction, causing sides to be concave. [8] [9] A twisted prism cannot be dissected into tetrahedra without adding new ...

The height h of an {n/d}-cupola or cupoloid is given by the formula: = (). In particular, h = 0 at the limits n / d = 6 and n / d = 6/5 , and h is maximized at n / d = 2 (in the digonal cupola : the triangular prism, where the triangles are upright).

3D model of a (uniform) heptagonal prism. In geometry , the heptagonal prism is a prism with heptagonal base. This polyhedron has 9 faces (2 bases and 7 sides), 21 edges, and 14 vertices.
The 5 Platonic solids are called a tetrahedron, hexahedron, octahedron, dodecahedron and icosahedron with 4, 6, 8, 12, and 20 sides respectively. The regular hexahedron is a cube . Table of polyhedra
The dual polyhedron of the triaugmented triangular prism has a face for each vertex of the triaugmented triangular prism, and a vertex for each face. It is an enneahedron (that is, a nine-sided polyhedron) [ 16 ] that can be realized with three non-adjacent square faces, and six more faces that are congruent irregular pentagons . [ 17 ]
