A triangular-based pyramid, also known as a tetrahedron, has no pairs of parallel faces. This is because all four faces (the triangular base and the three triangular sides) intersect with each other, and none of them are parallel to one another.
There are infinitely many polyhedra all of whose faces are triangular.
trianglesbecause TRIangular prism pyramid means that TRIangles are the bases, which also mean the faces.
If the base of the pyramid is a triangle then all its faces would be triangular in shape.

All except the base are always triangles; the shape of the base gives the name to the pyramid; eg a pentagonal pyramid has a pentagon as the base and five triangular faces; a triangular pyramid has three triangular faces and also has a triangle for the base.
It has 0. All of the faces intersect.
a pyramid has for faces and a base so all in all 5 faces the four on the outside are triangular and the base is square :)
A triangular pyramid has four faces, and is referred to as a tetrahedron if the faces ale all equilateral triangles.
