Prisms and pyramids are types of polyhedrons. A prism has congruent sides, while a pyramid has sides that decrease in size towards the top. To identify a shape as a prism or pyramid, look at the base polygon and use its name along with the term prism or pyramid, such as a pentagonal prism or octagonal pyramid. The only unique term is cube, which refers to a rectangular prism with six completely congruent faces.
Pyramids and prisms are polyhedra, with prisms having congruent bases and pyramids with diminishing shapes. Key shapes include triangular, square, pentagonal, and octagonal forms, with a focus on cubes.
