You need at least 4 faces for a pyramid. That type is known as Tetrahedron (http:/en.wikipedia.org/wiki/Tetrahedron)
yes
Not true. They have only one base and several (3 or more) lateral triangular faces. A pyramid has a single vertex over a base - there are no parallel faces in any pyramid.

A pyramid has triangular faces that converge at a single point called the apex. The base of the pyramid can be any polygon, and the number of triangular faces corresponds to the number of sides on the base. For example, a square pyramid has four triangular faces and a square base.

triangular pyramid
Number of faces on a square pyramid is 5.
A polyhedron with the fewest number of faces is a triangular pyramid - it has four faces including the base.
A pyramid can have 4 or more faces. A pyramid, with a n-sided polygon as base will have n+1 faces. The polygon with the least number of sides is a triangle and a triangular pyramid (tetrahedron) has 4 faces. A square based pyramid has 5 faces, and so on.
The most simple pyramid is a tetrahedron. This pyramid has four faces, all triangles. If the pyramid was a cone then it could have two faces.
7 faces.
If the number of vertices is not the same as the number of faces, it cannot be a pyramid.
A pyramid shape, by default, has a square base. It therefore has 5 faces.
what is the number faces does a triangular pyramid have
yes
Its shape, the number of faces edges and vertices.
