Star polygons in art and culture Star polygons in art and culture Star polygons and polygonal compounds are the basis for numerous figures of significance in arts and culture. The figure may be the border or interior of the polygon, or one or more closed polygonal paths that include all of the border and also have some legs crossing the interior. Impressions of astronomical stars provide the term, but specific uses may exploit the connection or not. Stars often represent the unity of states within a country when they are used as a part of the flag. The five-pointed star, if drawn with points of equal
Euclidean tilings by convex regular polygons vertex and one has an odd number of sides, the other two polygons must be the same. If they are not, they would have to alternate around the first polygon, which is impossible if its number of sides is odd. By that restriction these six cannot appear in any tiling of regular polygons: These four can be used in "k"-uniform tiling: Some of the "k"-uniform tilings can be derived by symmetrically dissecting the tiling polygons with interior edges, for example: Some k-uniform tilings can be derived by dissecting regular polygons with new vertices along the original edges, for example: There
