Both a cylinder and a prism can have parallel and congruent bases.
Prism!
A Base. * * * * * What? Every prism, by definition, has two congruent faces which may be called the bases of the prism.
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.
No, a prism cannot have curved sides. A prism is a polyhedron with two parallel and congruent polygonal bases connected by lateral faces that are parallelograms. The lateral faces of a prism are always flat, planar surfaces that are perpendicular to the bases. Curved sides would not meet the definition of a prism.
A prism has two congruent parallel bases.

A triangular prism.
Look at the prism. If all faces are rectangular (or square) then so are the bases. Otherwise they are the two congruent parallel faces that are not rectangular. Look at the prism.
