All shapes are polygons

Wrong! Neither is a polygons. Polygons are two-dimensional shapes enclosed by straight lines. Even a common shape, such as a circle is NOT a polygon.
Pyramids and prisms are two of an infinite variety of polyhedra.

A three sided trangle
pyramid (not including the vertex) Prism
Any. You can have a triangular pyramid (tetrahedron), a rectangular one, a pentagonal one, and so on. Similarly, you can have a triangular prism, a rectangular prism, and so on.
a prism is constructed from two parallel and congruent regular polygons. with vertices joined by edges of length equal to that of the polygons a pyramid has a square base and has 4 triangle joining at a vertex above the centre of the square base. the triangles are isosceles triangles (and can even be equilateral)
They are both polyhedra. Both have at least one hexagonal face. A 6-pyramid has only one hexagonal face, a 6-prism has 2. A 6-pyramid has only 7 face, a 6-prism has 8. A 6-pyramid has only 12 edges face, a 6-prism has 18. A 6-pyramid has only 7 vertices, a 6-prism has 12.
