none because a triangle is not a 3D object
The faces are the flat, triangle-shaped surfaces that make up the surface of the pyramid. A pyramid has four faces.

The three angles inside any triangle always add up to 180 degrees.If one of them is 90 degrees, then the triangle is a right triangle.

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.

No such thing as a 'square triangle'!!!! A Square has four sides , a triangle has three sides .
No.Faces relate to 3-dimensional objects, for example a tetrahedron, a cube. They are the 2-dimensional shapes that make up the surface of a 3-dimensional objectA triangle can be a face though, for example, a tetrahedron is made up of 4 triangular faces.
Think About It Its Like A TRIangle Or A TRIcycle

Three. There are three rectangles that are joined along their parallel edges which forms a triangle at each end.
