A polyhedron is a solid shape that has many flat faces. It can be made up of triangles, squares, rectangles, pentagons or any shape that has flat sides. Examples of polyhedrons include cubes, pyramids, and prisms. You can use the word when describing different shapes, such as when discussing geometry or when building models. It's a good word to know if you're interested in math or architecture, or if you just like to learn new words!
