A tetrahedron.
Tetrahedron
No, a polyhedron can have multiple bases. A base is a polygonal face that forms the bottom or top of the polyhedron, and there can be more than one base depending on the shape and symmetries of the polyhedron. For example, a prism has two parallel bases that are congruent polygons.

It is a pentagon.
It is a pentagon.
Cones and pyramids have only one base, but prisms have multiple bases.
A cone.

A tetrahedron.
Yes. A base on a polyhedron is a face and a base on a polygon is a side.
Tetrahedron
A polyhedron has only polygonal faces and any one of them can be considered a base. Therefore a polyhedron with 0 bases cannot exist.
No, a polyhedron can have multiple bases. A base is a polygonal face that forms the bottom or top of the polyhedron, and there can be more than one base depending on the shape and symmetries of the polyhedron. For example, a prism has two parallel bases that are congruent polygons.
This is a "trigonal pyramid" or "tetrahedron."
False, prisms can have more than one base.
