A polyhedron with two congruent and parallel faces.

A prism has two congruent parallel bases.
It is a polyhedron with two congruent faces: nothing more, nothing less. That can change if several additional conditions are required of the polyhedron.
Any regular polygon has two congruent faces. Many polygons have two or more congruent faces.
In a polyhedron - a 3-dimensional object - a pair of parallel faces are two faces which lie in planes that are parallel to each other.Parallel faces need not be congruent. For example, consider a pyramid whose top is sliced off by a plane parallel to it base. The flat top and the base will be parallel faces but will not be congruent.
A polyhedron that has two congruent faces is called a prism. It means that when it is cut at the cross-section, the shape is the same as its base.
A polyhedron that has 2 congruent faces is a PRISM. To be a prism, all the other sides (not including the 2 that are congruent) have to be 4-sided.
A Prismthe faces are called bases
Prism, which a polyhedron with two congruent and parallel faces (the bases) and whose lateral faces are parallelograms.
