How many triangles are there in a tetrahedron?

Best Answers

A regular tetrahedron is one in which all four faces are equilateral triangles. It is one of the five regular Platonic solids, which have been known since antiquity. In a regular tetrahedron, not only are all its faces the same size and shape (congruent) but so are all its vertices and edges. read more

There are three different solids that you can make with triangles. The first is the triangular pyramid, made of four sides, all triangles. Usually pyramids have five sides, four triangles and a square, such as the Great Pyramid in Giza, Egypt. This is an interesting shape, but it isn't a regular shape, since it uses a square as well as triangles. read more

Actually there might be infinite Triangles which can be accumulated within the bulk volume of a tetrahedral, since volume of a triangle is theoretically zero and any number greater than 0 divided z is practically infinite. read more
