Prisms and Pyramids
Prisms and pyramids are solid figures you see all around you. A prism has two identical bases and rectangular sides, like a milk carton, while a pyramid has one base and a pointed top with triangular sides, like an Egyptian pyramid. The number of base sides, n, sets how many vertices, edges, and faces there are, and folding a net back gives the same solid. Change n and rotate the figure to look at both shapes and their nets.
