Convex and non-convex polygons are classifications of polygons. But what are polygons? Polygons are closed-plane figures made up of line segments and the segments intersect only at their endpoints. If it does not satisfy the definition, then it is considered not a polygon. A three-dimensional figure is not a polygon since it is not anymore a plane figure. A plane figure has only two dimensions, namely, length and width. Also, a polygon’s sides must have exactly two other sides connected to them at their endpoints. All the sides must be line segments, not curve or circular in manner. Therefore, figures like circles, cones and the like are not polygons. So…
