A triangular pyramid is apyramid whose base is a triangle.
A triangular pyramid is a pyramid with a triangular base; all pyramids are by definition three-dimensional figures, so a triangular pyramid is indeed 3D.
A pyramid is a 3 dimensional object with a polygonal base (with n sides) and n triangular faces meeting at an apex above the base.
One, though it's technically a square - hence why it is called a square pyramid. By definition, a square pyramid has one square face. It also has four triangular faces which meet at the apex (the tip) of the pyramid.
It is a polyhedron with a pentagonal base. To every side of the pentagon are attached triangles that meet at a single point in a plane higher than the pentagon (if it is a skew pyramid, the apex will not be above the pentagon).
