The 3D shapes that have all their faces equal to their base are known as regular polyhedra. Specifically, these include the tetrahedron (4 triangular faces), cube (6 square faces), octahedron (8 triangular faces), dodecahedron (12 pentagonal faces), and icosahedron (20 triangular faces). Each of these shapes features congruent faces that exhibit symmetry.
A square pyramid has a square base and four congruent triangular faces.
2 shapes, a triangle, and a rectangle.since it is a prism, it is like a pyramid, 4 of the faces are triangles,but the base is a rectangle, hence the name rectangularprismtherefore, 2 shapes
There is a contradiction in your question. If the base has four equal sides then is it a square so not all the faces are Triangles. However if the base is a square and the rest of the faces are triangles then your object is a "Square-based Pyramid"
Two shapes with five faces are a triangular prism and a square pyramid. A triangular prism consists of two triangular bases and three rectangular lateral faces, while a square pyramid has a square base and four triangular faces that converge at a single point (the apex). Both shapes exemplify polyhedra with five distinct surfaces.
The answer to your question, is an Octahedron.
The most common pyramid shapes have 3 faces on a triangular base or 4 faces on a square face. Other pyramid shapes may have more faces corresponding to the shape of the base.
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 square pyramid has a square base and four congruent triangular faces.
A Triangular Pyramid, 3 faces, 1 base.
A square pyramid has a base with 4 equal sides and triangular faces.

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.
One square or rectangle as it's base, and the other sides are triangles.

Two: a pentagonal base and 5 triangular faces. The triangles need not all be the same and if you count them as different shapes, there will be six shapes in all.
