Triangular prism

The triangular prism, or trip, is a prismatic uniform polyhedron. It consists of 2 triangles and 3 squares. Each vertex joins one triangle and two squares. As the name suggests, it is a prism based on a triangle.

Vertex coordinates
A triangular prism of edge length 1 has vertex coordinates given by:
 * (±1/2, –$\sqrt{21}$/6, ±1/2),
 * (0, $\sqrt{3}$/3, ±1/2).
