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.
It is a tetrahedron which is a triangular based pyramid
A triangular based pyramid (tetrahedron) has 4 triangular faces, 6 edges and 4 vertices.
That 3D shape is called triangular pyramid.
The solid shape that has one square face and four triangular faces is called a pyramid. If you were to have a shape that had four triangular faces and no square face, it would be called a triangular pyramid.
