A tetrahedron is a four sided polyhedron. Each face is a triangle. If it is a regular tetrahedron, then each face is an equilateral triangle.
A regular polyhedron has equal size faces as in the case of a tetrahedron which is a triangular base pyramid that has 4 equilateral triangle faces.
No, tetrahedron is a polyhedron with four faces.
Yes. A polyhedron is a geometric shape with flat surfaces and straight edges, so a a pyramid with a rectangular base qualifies as a polyhedron. It is however not a regular polyhedron, which would require all the faces to be the same shape and size. To change your pyramid to a regular polyhedron you'd have to turn it into a tetrahedron.
No, tetrahedron is a polyhedron with four faces.
Yes and its names is a tetrahedron.

In geometry, an octahedron is a polyhedron with eight sides. A regular octahedron is the dual polyhedron of a cube; It is a rectified tetrahedron.
Square Based PyramidTetrahedron: A tetrahedron is a polyhedron made of 4 triangles. A "regular tetrahedron" is a tetrahedron where the triangles are equilateral. (A polyhedron is any 3 dimentional figure made of flat surfaces and straight lines.)
