WebA non-polyhedron is a space figure that has at least one face or component that is not a polygon. In geometry, three types of non-polyhedra that are commonly studied are cylinders, cones, and spheres. Cylinder. A cylinder is a 3D shape that is made up of two flat circular bases and a curved surface that "wraps" around the bases. WebRegular Polyhedron. A polyhedron is said to be a regular polyhedron if its faces are made up of regular polygons and the same number of faces meet at each vertex. This means that …
