No, tetrahedron is a polyhedron with four faces.
There is no such shape. A tetrahedron has 6 edges, but it is NOT a prism.
Pentagon (and in 3d: triangular prism and tetrahedron.)
A regular tetrahedron. octahedron, dodecahedron.
2 - a Triangular Prism has 6, a Triangular Pyramid (Tetrahedron) has 4.
No.
No, tetrahedron is a polyhedron with four faces.
No, it is not.
rectangular prism
There is no such shape. A tetrahedron has 6 edges, but it is NOT a prism.
A triangular prism is a pentahedron, a triangular pyramid is a tetrahedron.
A tetrahedron is a polyhedron with four triangular faces, while a triangular prism is a polyhedron with two triangular faces and three rectangular faces. The main difference between the two shapes is their number of faces and their base shapes. Additionally, a tetrahedron has four vertices and six edges, while a triangular prism has six vertices and nine edges.

A regular tetrahedron. octahedron, dodecahedron.
Triangular prism * * * * * No. It is a triangular pyramid or a tetrahedron. A triangular prism has 6 vertices and 5 faces.
2 - a Triangular Prism has 6, a Triangular Pyramid (Tetrahedron) has 4.
Any. You can have a triangular pyramid (tetrahedron), a rectangular one, a pentagonal one, and so on. Similarly, you can have a triangular prism, a rectangular prism, and so on.
