all the bases of a pyramids are polygon
All polyhedrons.
no
Many 3-d figures can have polygons for bases. If all ist faces are polygons then it is a polyhedron but it is possible to have 3-d figures with a polygonal base and non-polygonal faces.
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.
No, none of them do.
No.

A right prism.
It is simply a shape which has two bases which are regular polygons. There is no special name for such shapes.
All pyramids have only one base.
A cylinder has circular parallel bases
In math pictures, there are several types of pyramids, primarily categorized by their base shapes. The most common types are triangular pyramids (tetrahedrons) with triangular bases, and square pyramids with square bases. Additionally, pyramids can have other polygonal bases, such as pentagonal or hexagonal. Each type of pyramid maintains a vertex at the apex, connecting to all vertices of the base, forming triangular faces.
