A tetrahedron is a four sided polyhedron. Each face is a triangle. If it is a regular tetrahedron, then each face is an equilateral triangle.
Each face has three edges.
They don't have names beyond "the faces of the tetrahedron."

A tetrahedron must be plane faced and so, it is just an ordinary tetrahedron.

Yes it is a tetrahedron

A tetrahedron has 4 vertices's, 6 edges, and 4 faces. Each face is a triangle.It looks like a triangle based pyramid.
No.
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.

Take four non-coplanar points. "Join" each triplet with a triangular face.
