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 triangular bipyramid is the dual polyhedron of a triangular prism, and vice versa. [17] [3] A triangular prism has five faces, nine edges, and six vertices, with the same symmetry as a triangular bipyramid. [3]
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 ...

A square antiprismatic prism or square antiduoprism is a convex uniform 4-polytope. It is formed as two parallel square antiprisms connected by cubes and triangular prisms. The symmetry of a square antiprismatic prism is [8,2 +,2], order 32. It has 16 triangle, 16 square and 4 square faces. It has 40 edges, and 16 vertices.
The elongated triangular bipyramid is constructed from a triangular prism by attaching two tetrahedrons onto its bases, a process known as the elongation. [1] These tetrahedrons cover the triangular faces so that the resulting polyhedron has nine faces (six of them are equilateral triangles and three of them are squares), fifteen edges, and eight vertices.
