If it also has two triangular faces, then a triangular prism. If it has only three rectangualr faces, there is no such shape.
The only one i can think of is the square - based pyramid, with 4 triangular faces and 1 square
No, a dodecahedron is a 3-dimensional shape. Some of the 6.4 million topologically distinct dodecahedra have only triangulat faces, there are many more in which some faces, but not all, are triangular.
You can't have a 3-d shape with only 2 faces. A triangular prism has 9 edges and 6 vertices, but it has 5 faces.
Triangular prisms have two triangular bases (parallel to each other) that are connect by three rectangles. Therefore, it has 5 faces (the flat shapes described earlier), 6 vertices (the corners where more than 2 faces meet), and 9 edges (the segments where only two faces meet).

There is no shape with only four triangular faces and five vertices. If there is also a quadrilateral face then it is a quadrialteral based pyramid.
A square or rectangular pyramid.NO. The above have four triangular faces PLUS a square or rectangular face. A tetrahedron has only four faces, all of which are triangular.A triangular based pyramid has 4 triangular faces, 6 edges and 4 vertices
A 3D shape with one base and three faces can only have triangular faces.
Triangular prisms have two triangular bases (parallel to each other) that are connect by three rectangles. Therefore, it has 5 faces (the flat shapes described earlier), 6 vertices (the corners where more than 2 faces meet), and 9 edges (the segments where only two faces meet).

A shape with 5 sides is a pentagon.However, the term face is only applied to three-dimensional forms,and a shape (solid) with 5 faces is a pentahedron.There are no regular pentahedrons. The two forms are the square pyramid and the triangular prism. The former has 4 triangular sides and a square or rectangular base; the latter has 3 rectangular (or square) faces and two triangular ends.
An icosahedron is a shape with 20 triangular faces - not more nor fewer. It can, therefore, have only 20 tall isosceles triangular faces.
An icosahedron is a shape with 20 triangular faces - not more nor fewer. It can, therefore, have only 20 short isosceles triangular faces.
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.
