It is a pentagon.
The base of a pentagonal prism is a pentagon. Just like a square pyramid has a square for a base, a pentagonal prism has a pentagon for a base.

In general, any 10-sided polyhedron is called a decahedron. With 10 regular triangles for faces, you may have a pentagonal bipyramid.
Pentagonal pyramids have six faces, ten edges, and six vertices. One of the faces is a pentagonal base, the rest are triangular.

It is a polyhedron with a pentagonal base. To every side of the pentagon are attached triangles that meet at a single point in a plane higher than the pentagon (if it is a skew pyramid, the apex will not be above the pentagon).
A pentagonal is not a shape. You an have a pentagonal pyramid, a pentagonal prism or a pentagonal polyhedron as well as other shapes - each would give a different set of answers.
A polyhedron is a 3-dimensional object comprising a space enclosed by a number of polygons. In general, these polygons are called faces: in some polyhedra they are also called bases. They may or may not be triangular. A pentagonal prism, for example, has no triangle face and so no triangular base.
The base of a pentagonal prism is a pentagon. Just like a square pyramid has a square for a base, a pentagonal prism has a pentagon for a base.

Cube (hexahedron) has square faces and dodecahedron has pentagonal faces.
