The Difference between Prism and Pyramid is given here. In geometric terms, a prism and a pyramid are different structures. Prism has two congruent bases, while a pyramid has one base.
Using the terms synonymously is rare, but it is important to know the prism and pyramid definitions.
What is Prism?
A prism is a polyhedron with a polygonal base with n quantities of sides, a translation copy (it is not in the same plane as the first one) and other n parallelogram faces that join both sides of the corresponding ones of both bases. The parallel cross-sections of a prism can be split into two forming a triangle and a square on the faces of the base. A prism is a subclass of prismatoids.
A prism gets its name from the shape of its base, for example, a prism with a pentagonal base is called a pentagonal prime. A prism with edges and junctions parallel to each other and faces perpendicular to the face of the base is called a right prism. An oblique prism is one where the faces are not perpendicular to the face of the base. As a prism increases its number of faces n and this number approaches infinity, then the prism becomes a cylinder.
What is Pyramid?
Pyramids are polyhedra, they are made up of a polygon or base and a number of triangles on each side of the polygonal base. All the triangles converge at a point called the vertex of the pyramid. The triangles of a pyramid are called lateral faces and the common side between them is called the edge. A pyramid is made up of a base, vertex, edge, and height. There are several types of pyramids such as the oblique pyramid and the square pyramid.
Main differences between Prism and Pyramid

Similarities between Prism and pyramid
- Both prism and pyramid have 3-dimensional shapes.
- All the sides of the prism and pyramid meet at the bases.
- Both pyramids and prisms do have not round sides.
- Both are solid Geometrical shapes.
- Both have flat bases.

Difference between Prism and Pyramid in points
- A prism is a polyhedron with a polygonal base and n number of sides.
- A pyramid is a polyhedron with a base made up of a polygon and sides made up of the number of triangles depending on the number of sides of the polygon.
