text: A prism is a solid, whose side faces are parallelograms and whose bases are congruent parallel rectilinear figures.
text: When the bases don't align with eachother, then the prism is an oblique prism, and the faces between the bases are parallelograms, as opposed to rectangles.
text: A polyhedron is called an $n$-gonal prism if two of its faces (the bases) are equal $n$-gons (not lying in the same plane), which can be obtained from each other by parallel translation, and the remaining faces are parallelograms, the opposite sides of which are the corresponding sides of the bases.
