A tetrahedron (4 faces) and an icosahedron (20).

Only one; a triangle is a 2D shape, not a 3D shape. Usually only 3D (or more) shapes are considered to have '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

Triangle Pentagon Septagon Nonagon Etc

it has 4 faces and each face is a triangle.

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.

They are all rectangles.

A icosahedron has twenty faces.It has 20 faces.It has 20 triangle faces.Its faces are always triangles.Wow! Harsh! Super Shapes! Correct!

There are infinitely many such shapes. A tetrahedron is one example.
