a triangular based pyramid
The rectangular pyramid got its name through its base, a rectangle.
A square pyramid's base is a square. You can tell by the name (for exp. a triangular pyramid's base is a triangle.) Good luck with whatever you need it for :)

It has 5 faces. The "quadrilateral" part of the name describes the shape of the base of the pyramid. A pyramid has 1 face for every side of the base plus an extra one for the base. Thus a quadrilateral pyramid has a quadrilateral or 4 sided shape for the base and so has 4 + 1 = 5 faces.
It has a pentagon base and it is a pyramid
a triangular based pyramid
The scientific name for a square base pyramid is a "square pyramid." It is a type of pyramid where the base is a square and the triangular sides meet at a common apex point.
The rectangular pyramid got its name through its base, a rectangle.
A square pyramid's base is a square. You can tell by the name (for exp. a triangular pyramid's base is a triangle.) Good luck with whatever you need it for :)
Because its base is a square.
All except the base are always triangles; the shape of the base gives the name to the pyramid; eg a pentagonal pyramid has a pentagon as the base and five triangular faces; a triangular pyramid has three triangular faces and also has a triangle for the base.
A six sided cone is a pyramid technically, and it would be a hexagonal pyramid (if six sides does not include base) or a pentagonal pyramid (if including base.)

A square based pyramid is the best name. It is a pentahedron, but that could also refer to a pyramid on any quadrilateral base and so the name is far less informative.
One base, which is a pentagon.
It has 5 faces. The "quadrilateral" part of the name describes the shape of the base of the pyramid. A pyramid has 1 face for every side of the base plus an extra one for the base. Thus a quadrilateral pyramid has a quadrilateral or 4 sided shape for the base and so has 4 + 1 = 5 faces.
