the difference between a pyramid and prism (in geometry) is that a pyramid has one base and lateral faces that are triangles where prisms have two congruent bases and lateral faces that are parallelograms
A triangular prism or a cuboid as it seems would fit the given description
A rectangular prism has congruent bases and parallelograms as lateral surfaces.
The lateral sides are usually rectangles so each would comprise four right angles. However, the bases can be any pair of congruent triangles.
In a tetrahedron all the triangles have to be congruent. In a Triangular Pyramid, the lateral faces are all congruent to each other, but not always with the base triangle. Not necessarily. The lateral faces need to be congruent if it is a right pyramid, not otherwise. The apex of the pyramid need not be directly above the centre (however defined) of the base. Think of a triangular pyramid doing an impersonation of the Leaning Tower of Pisa!
