Because that example, the base might have a square, rectangle, triangle, hexagon, pentagon or octagon shape. The base is never a circle or one oval on a prism or a pyramid.

The side-by-side faces, also known together lateral faces, ~ above pyramids and prisms have different attributes. **Prisms have rectangular lateral faces and pyramids have triangular lateral faces.** In most cases, the lateral encounters of both prisms and pyramids room angled toward the basic or bases. The rare exception is the "right prism" -- the encounters are perfect perpendicular come the base. The lateral deals with are congruent triangle on a "right pyramid."

Pyramids different from prisms due to the fact that they have one main vertex, frequently referred to together an apex or a point, where the lateral faces meet. **The peak is directly over the facility of the base, nevertheless of the shape of the base**. Prism don"t have actually a vertex since there room multiple conference points where the faces connect.
