The answer depend on the truncation but assuming it is by a plane parallel to the base, the truncated tetrahedron is like a triangular prism (except that one base is smaller than the other). It, therefore, has 5 faces, 6 vertices and 9 edges.
A tetrahedron has 6 edges.
A tetrahedron is a triangular based pyramid that has no parallel edges whereas most prisms have parallel edges such as a cuboid or a cylinder.
