A tetrahedron is a triangular based pyramid that has 4 faces, 6 edges and 4 vertices
A cantellated regular tetrahedron, in the form of a regular cuboctahedron, has 14 faces (8 triangular, and 6 square), 24 edges and 12 vertices.
A truncated tetrahedron has eight 8 faces: 4 hexagonal faces and 4 triangular faces.
Tetrahedron in geogmetry is composed of four triangular faces, three of which meet at each vertex.
There are five Platonic solids: Tetrahedron (or triangular pyramid): 4 triangular faces Cube: 6 square faces Octahedron: 8 triangular faces Dodecahedron: 12 pentagonal faces Icosahedron: 20 triangular faces. Although not a Platonic solid, some people consider a sphere to be a regular 3d shape.
A tetrahedron is a triangular based pyramid that has 4 faces, 6 edges and 4 vertices
In geometry, a tetrahedron is a solid with four faces, which is a triangular pyramid (don't forget the base-face), and a regular tetrahedron has (4) faces that are equilateral triangles.

A tetrahedron has 4 faces. A "regular tetrahedron" has an equilateral triangular base with three equilateral triangles as sides coming up from it.
A cantellated regular tetrahedron, in the form of a regular cuboctahedron, has 14 faces (8 triangular, and 6 square), 24 edges and 12 vertices.
Four triangular faces.
There are many possible shapes. The regular ones amongst them are the tetrahedron, the octahedron and the icosahedron.
A truncated tetrahedron has eight 8 faces: 4 hexagonal faces and 4 triangular faces.
