Isosceles Tetrahedron
A solid with four faces is a tetrahedron. Each of the faces is a triangle. If all the triangles are congruent, you have an isosceles tetrahedron.
A prism??? O.o sounds like it to me anyway...

Well if you mean triangular pyramid and triangular prism then: A triangular pyramid is a geometric solid with a base that is a triangle and all other faces are triangles with a common vertex. A triangular prism is a geometric solid with two bases that are congruent (identical), parallel triangles and all other faces are parallelograms. It is referred to as a right triangular prism if the faces are rectangles.

A triangular prism. :)
It is a prism. More specifically, "A solid figure that has two bases that are parallel, congruent polygons and with all other faces that are parallelograms." This describes the general prism. Replace "polygons" with "triangles" and you have specified a triangular prism.
A solid with six congruent square faces is a cube.
The description given could fit that of a triangular prism.
A tetrahedral prism is a three-dimensional geometric shape that has two congruent triangular bases and four congruent lateral faces that are in the shape of triangles. The lateral faces connect the corresponding vertices of the two triangular bases, forming a solid with six faces, eight edges, and four vertices.
