In geometry a simple polygon /ˈpɒlɪɡɒn/ is a flat shape consisting of straight, non-intersecting line segments or 'sides' that are joined pair-wise to form a closed path. If the sides intersect then the polygon is not simple. The qualifier 'simple' is frequently omitted, with the above definition then being understood to define a polygon in general.
