four triangle faces.
A three dimensional triangular figure with three faces and a base is called a triangular pyramid. It has four vertices, four faces, and six edges.
By its very nature of being a triangle, and a 2D shape, a triangle cannot have four plane faces. However, a tetrahedron is a polyhedron made up of four triangular faces.
The face of a triangle is the flat surface of the solid figure. _________________________________________________ A face is a side of a 3 dimensional figure. So, the number of faces a triangle would be 0.
