Triangular prism

A triangular prism or trigonal prism is a prism with two triangular bases in geometry. If the edges pair with each triangle's vertex and if they are perpendicular to the base, the triangular prism is a right prism. A right triangular prism may be both semiregular and uniform. The triangular prism can be used as the core of constructing other polyhedra, examples are some of the Johnson solids and Schönhardt polyhedron. It has a relationship with the honeycombs and polytopes. It can be found in many real-life applications as in architecture and natural science.
