A Pyramid is a 3

In geometry, pyramids and prisms are two different shapes. The main difference between a pyramid and prism is the fact that a prism has two bases, while the pyramid only has one.

Bases

A right prism is a prism in which the joining edges and faces are perpendicular to the base faces. This applies if the joining faces are rectangular. If the joining edges and faces are not perpendicular to the base faces, it is called an oblique prism.

More About The Side Faces

Prisms have rectangular lateral faces and pyramids have triangular lateral faces. In most cases, the lateral faces of both prisms and pyramids are angled toward the base or bases. The rare exception is the "right prism" -- the faces are perfectly perpendicular to the base.

More About The Side Faces

More About The Side Faces. The side faces of a prism are parallelograms (4-sided shape with opposites sides parallel) A prism can lean to one side, making it an oblique prism, but the two ends are still parallel, and the side faces are still parallelograms! But if the two ends are not parallel it is not a prism.

Right Pyramid

A prism is also a three-dimensional polyhedron, but it looks very different from a pyramid. A prism has two identical ends and all flat sides. The sides or faces are perpendicular to the base faces, i.e. they make a right angle with the base.

Sides

Prism (geometry) In geometry, a prism is a polyhedron comprising an n-sided polygonal base, a second base which is a translated copy of the first, and n other faces (necessarily all parallelograms) joining corresponding sides of the two bases.

Sides

A truncated prism is a prism with nonparallel top and bottom faces. Some texts may apply the term rectangular prism or square prism to both a right rectangular-sided prism and a right square-sided prism. A right p-gonal prism with rectangular sides has a Schläfli symbol { } × {p}.

These are all Prisms: Square Prism:

All the previous examples are Regular Prisms, because the cross section is regular (in other words it is a shape with equal edge lengths, and equal angles.) Here is an example of an Irregular Prism: Irregular Pentagonal Prism:
