A tetrahedron is a triangular based pyramid that has 4 faces, 6 edges and 4 vertices
There are four number of faces in a tetrahedron.
A pyramid with a triangle as base is considered as a tetrahedron. It is a three dimensional polyhedron with 4 equilateral triangles as its sides. If one would look at the word tetrahedron, it literally means "with four planes".
A tetrahedron is a 3-dimensional shape - a triangular pyramid. It is NOT a number.
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.
A tetrahedron is a 3-D shape. It has a different number of faces and edges and does not represent any particular number.

The answer depends on the number of point. One point - as the question states - cannot be non-collinear. Any two points are always collinear. But three or more points will define a plane. If four points are non-coplanar, they will define four planes (as in a tetrahedron).

You need at least 4 faces for a pyramid. That type is known as Tetrahedron (http:/en.wikipedia.org/wiki/Tetrahedron)
