WebA cylinder is a 3D solid shape that consists of two identical and parallel bases linked by a curved surface. Polygons are defined as plane (two-dimensional) and closed shapes that are formed by joining three or more line segments with each other. From the definition of polyhedron, line segments meet at edges. WebA cylinder is a surface that consists of two congruent simple closed curves lying in parallel planes and the segments that connect them. If these simple closed curves were polygons, then the cylinder would be a prism. Here is a drawing of a cylinder.
