They do not have names.
A tetrahedron or triangular pyramid.
If restricted to plane faces, a rectangular pyramid or a triangular prism. With curved faces such shapes will usually not have names.
There are 3 rectangular faces and 2 triangular faces. The triangles are the bases.
NO such thing as a triangular pyramid. A PYRAMID has a square base, upon which four triangles are mounted, to form a peak. A TETRAHEDRON has a triangular base and three triangular faces mounted on it.
Tetrahedron.

4 faces: tetrahedron; a pyramid with a triangular base has 4 faces.5 faces: pentahedron; A triangular prism (the sort you make a rainbow with) is a pentahedron; a square pyramidis a pentahedron - it has a square base and 4 triangular sides.6 faces: hexahedron; a regular hexahedron, with all its faces square, is a cube. 7 faces: heptahedron 8 faces: octahedron9 faces: enneahedron10 faces: decahedron11 faces: hendecahedron 12 faces: dodecahedron
trangular prism NO! A prism has two n-polygonal faces (or bases) "separated" by a set of n rectangles. A pyramid has one n-polygonal face (base), with n triangular faces rising to an apex. Some pyramids do have specific names but in general, they do not.
