a prism is a polyhedron with two congruent faces, called bases, that lie in parallel planes. The other faces, called lateral faces, are parellelograms formed by connecting the corresponding vertices of the bases. the segments connecting the vertices are lateral edges. the altitude, or height, of a prism is the perpendicular distance between its bases.

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.
hexagonal prism
The bases of a prism or cylinder are congruent and parallel and they meet the lateral face (cynder) or faces (prism) at right angles. A cross section parallel to the longitudinal axis will, therefore, be a rectangle.
Not true. They have only one base and several (3 or more) lateral triangular faces. A pyramid has a single vertex over a base - there are no parallel faces in any pyramid.
perpendickular
Prism, which a polyhedron with two congruent and parallel faces (the bases) and whose lateral faces are parallelograms.
