Not true.
no not all pyramids are polyhedron because each pyramid has a different shape. so no each pyramid is not a polyhedron * * * * * Yes they are.
Triangles, pyramids, and prisms can all have triangular shapes.

Both pyramids and prisms are three dimensional. Both of them have polygon faces. Another thing common about pyramids and prisms is that they have a base and faces.
Triangular prisms and square-based pyramids have 5 faces. Trapezoid prisms and cubes have 6 faces. Hexagonal prisms and octahedrons have 8 faces.

Prisms are a subset of polyhedra (or polyhedrons!)

i am not sure.
