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.
Square Pyramid has a square base and 4 triangular sides. Triangular Pyramid has a triangle base and 3 triangular sides.
A square pyramid has five faces. There is the square that forms the base, and four triangular sides.
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.
A triangular prism has a triangular base. A square-based prism has a square base. A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges.
A triangular prism can have a square or triangular base, but faces are normally triangles. (I think)
It is a square pyramid.
A square-based pyramid
A square pyramid.
A square pyramid if all triangular faces converge to a point.
The geometric shape that has 1 square face and 4 triangular faces is a pyramid. A pyramid also has five vertices and eight edges. The square acts as the base for the shape on which it sits.
A triangular pyramid has a triangular base and three triangular faces meeting at its apex. A square pyramid has a square base and four triangular faces meeting at its apex.
It is a pyramid
A triangular prism can have a square or triangular base.
A pyramid - it has a square base, and four triangles meeting to a point at the top.
That would be a triangular pyramid.
