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.

No. The faces of a tetrahedron are equilateral triangles, but none of the faces is parallel to another one of the faces -- they could not be parallel, since by the definition of a tetrahedron, all the faces intersect(!) and parallel planes do not intersect.
