2. Pyramid A pyramid has its base as any polygon and its side faces are triangles with a common vertex (known as apex). If the base of a pyramid is an n-sided polygon, then it has (n+1) faces, (n+1) vertices, and 2n edges. 3. Platonic Solids In Platonic solids, all the fac...
a dodecahedron has 12, and so forth. Sometimes, descriptive terms about the shape will be added as well. A pyramid, for example, is a special type of four or five sided polyhedron. Stellated polyhedrons have numerous pyramidal outcroppings called stellations that...
