In a prism there are two equal and similar end faces, parallel to each other, joined together by other rectangular faces. In some cases, the faces joining the end faces may be parallelograms instead of rectangles. There are many types of Prism, and they are named after the shape of their base. A prism having pentagonal base faces is called a pentagonal prism. It is a type of heptahedron with 7 faces, 15 edges, and 10 vertices.

Pentagonal Prism

The prisms are named after the base. If the base is a triangle, the prism is called right triangular prism. If the base is a pentagon, the prism is right pentagonal prism. A prism having pentagonal end faces is called a pentagonal prism.

Regular Pentagonal Prism

A right regular prism is the right angled prism whose all lateral faces are equal rectangles. The end faces of the regular prism are regular polygons. Similarly, a regular pentagonal is the right angled prism whose all lateral faces are equal rectangles and end faces of the regular pentagonal prism are regular pentagons.

Oblique Pentagonal Prism

A oblique prism is a prism in which the parallel lateral edges are oblique to the base edges at their points of intersection. Oblique pentagonal prism, the prism whose axis is inclined to the end faces called an oblique prism.
