# Definition of Prism

A **prism** is a three-dimensional object, both ends of which are identical.

Every cross-section of a prism has the same shape as the ends.

Prisms are one form of polyhedron.

Each side of a prism is a parallelogram. If the two ends are exactly over each other, then the sides are rectangles and we call the prism a "right prism".

The shape of the base of a prism gives the solid its name. For example, if the base is a pentagon, then the prism is called a pentagonal prism.
