It would obviously be false
A prism has two congruent parallel bases.
An upright pentagonal prism has two congruent parallel bases and 15 edges.
It can, but need not. Only a right prism must.

Prism, Cylinder, and Cube
A prism has two congruent parallel bases.
Both a cylinder and a prism can have parallel and congruent bases.
They are a pair of congruent and parallel faces of a prism.
Each and every prism has two parallel congruent bases. It is the shape of these bases that give the name to the prism: a pentagonal prism has pentagons (not necessarily regular) for its bases.

An upright pentagonal prism has two congruent parallel bases and 15 edges.
It could be a prism, but need not be. A regular dodecahedron, for example, is not a prism but has parallel and congruent pentagonal bases. You can also have any antiprism (see link).
A rectangular prism has congruent bases and parallelograms as lateral surfaces.
It can, but need not. Only a right prism must.
