equilateral triangles
The faces of a tetrahedron are all triangular polygons. Specifically, a regular tetrahedron has equilateral triangles as its faces, while an irregular tetrahedron can have any type of triangle as its faces, but they will always be triangular in shape. Each tetrahedron has four triangular faces, four vertices, and six edges.
You need at least 4 faces for a pyramid. That type is known as Tetrahedron (http:/en.wikipedia.org/wiki/Tetrahedron)
There are four number of faces in a tetrahedron.
They don't have names beyond "the faces of the tetrahedron."
A triangular pyramid has four faces, and is referred to as a tetrahedron if the faces ale all equilateral triangles.

A tetrahedron has four faces. Each face is a triangle, and the tetrahedron is a type of polyhedron that is the simplest three-dimensional shape. It also has four vertices and six edges.
A truncated tetrahedron has eight 8 faces: 4 hexagonal faces and 4 triangular faces.
