Prism

My Definition

Key Characteristics

The following are true of a prism:

- It has two parallel and congruent polygonal bases.
- Its lateral faces are parallelograms.
- It is named for the shape of its base. For example, a pentagonal prism would have pentagonal bases.
- It has faces, vertices, and edges that can be counted.
- Parallel line segments connect corresponding points on the two bases.
- If a plane intersects the prism and is parallel to the bases, the cross section is congruent to each of the bases.
