No. A polyhedron is a three dimensional body. The base of a pyramid is a two dimensional figure.
But any non self-intersecting polygon can be the base of a pyramid.
No, the base of a pyramid must be a 2-dimensional shape so no polyhedron can be its base.
It can be any type of pyramid.
A pyramid, as well as any other solid figure bounded by plane polygons or faces, is a polyhedron.
Yes. A polyhedron is a geometric shape with flat surfaces and straight edges, so a a pyramid with a rectangular base qualifies as a polyhedron. It is however not a regular polyhedron, which would require all the faces to be the same shape and size. To change your pyramid to a regular polyhedron you'd have to turn it into a tetrahedron.
A polyhedron with a polygon base and triangular sides that all meet at a common vertex is known as a pyramid. The base can be any polygon, such as a triangle, square, or pentagon, and the triangular sides are called lateral faces. The vertex where all the triangular faces converge is referred to as the apex of the pyramid. Each type of pyramid is named based on the shape of its base, such as a triangular pyramid or a square pyramid.
Any polygon can be the base of a pyramid and so any polygon can form a polyhedron.
No, the base of a pyramid must be a 2-dimensional shape so no polyhedron can be its base.
It can be any type of pyramid.
No, it cannot.

A Pyramid; Four sides and the base.
A polyhedron with a polygonal base and triangles for sides.
A pyramid, as well as any other solid figure bounded by plane polygons or faces, is a polyhedron.
Yes. A polyhedron is a geometric shape with flat surfaces and straight edges, so a a pyramid with a rectangular base qualifies as a polyhedron. It is however not a regular polyhedron, which would require all the faces to be the same shape and size. To change your pyramid to a regular polyhedron you'd have to turn it into a tetrahedron.
A pyramid has a polygonal base with all other sides being triangles. As the Egyptians famously demonstrated, a common pyramid has a square base with four triangles meeting at a vertex, but any polygon - regular or irregular - can be used as the base of such a polyhedron.
