A regular tetrahedron
Well, a tetrahedron has four sides. A regular tetrahedron is a triangular pyramid.
A tetrahedron must be plane faced and so, it is just an ordinary tetrahedron.

A tetrahedron has 4 vertices and 4 sides. Each side is an equilateral triangle. * * * * * Each face is an equilateral triangle only if it is a regular tetrahedron; there is no reason to assume it is.
A tetrahedron is made up of 4 triangular faces, 3 of which meet at each corner or vertex. This is sometimes called a pyramid.
