Any face of a tetrahedron can be considered a base. A pyramid, in general, has one polygonal face (with n sides) and n triangular faces. In such a pyramid, the triangular faces would normally not be considered bases - only the n-gon would.
The short answer is no. Strictly speaking, a pyramid is the generic term. A pyramid has a base formed from a polygon connected to a point called the apex. A tetrahedron is a pyramid with the base of a triangle. Thus a tetrahedron is a specific example of a pyramid.
No. A cone could be considered the limiting case of a pyramid, but a hemisphere is not, because the lines joining the base to the apex are not straight.
A pyramid (3D)! Some examples: - triangular base pyramid - square base pyramid - rectangular base pyramid - cone
A pyramid has a square base.
The base of a square pyramid is a square. The pyramid has 4 faces making the base have four edges. SQUARE PYRAMID
Neither a triangular nor a rectangular pyramid has a square base. A square pyramid has a square base.

Depends on the pyramid. A pyramid with a square (or quadrilateral) base would indeed have 8 edges, but a pyramid can have any other polygon as a base.Depends on the pyramid.

There are three Giza pyramids, the Pyramid of Khafre, the Pyramid of Menkaure, and The Great Pyramid of Giza. The base size for the Pyramid of Khafre is 706ft. The base size for the Pyramid of Menkaure is 215ft. They base size for The Great Pyramid of Giza is 756ft.
the base of a triangular pyramid is triangle
A pyramid with a triangular base is a tetrahedron
