a triangular pyramid.
The shape that has 8 triangular faces and 12 edges is known as a triangular prism. In a triangular prism, two triangular faces are connected by three rectangular faces, but when considering only the triangular faces, it can also refer to a more complex polyhedron, specifically a truncated tetrahedron, which has 4 triangular faces and 4 hexagonal faces. However, if strictly adhering to the triangular face count, the triangular prism fits the description as it has triangular faces as part of its structure.

tetrahedron
There are an infinite no of shapes that have exactly 4 triangular faces. The two commonest are a tetrahedron and an Egyptian pyramid. If the question is re-phrased to "What shape has exactly four faces, (all of which are triangular), then the only answer is a tetrahedron. An Egyptian pyramid has five faces - a square base and four triangular sides. It is regular (the apex is vertically above the center of the base) and the sides are isosceles.
