In geometry, a tetrahedron (plural: tetrahedra or tetrahedrons) is a polyhedron composed of four triangular faces, three of which meet at each corner or vertex. It has six edges and four vertices. The tetrahedron is the simplest of all the ordinary convex polyhedra and the only one that has fewer than 5 faces. The tetrahedron is the three-dimensional case of the more general concept of a Euclidean simplex.
Best Answer: Vertices are points where two lines meet. For example, a square has 4 vertices. A cylinder is comprised of circles, so there is only one line [instead of two lines to meet], so there are NO VERTICES. Faces are sides of a 3-D object. For example, a cube has 6 faces--a top, a bottom, and 4 sides. A cylinder has a top, bottom, and the middle is one face = 3 FACES.
