are the sides of a regular (n, k)-gon (see Fig. 1). The regular (n, 1)-gon is an ordinary regular n-gon with directed sides. The regular (n, n − 1)-gon is the same ordinary regular n-gon, only the orientation of the sides are the opposite. For 2 ≤ k ≤ n − 2 a regular (n, k)-gon is a star polygon. An affine regular (n, k)-gon is an affine image of a regular (n, k)-gon (see Fig. 2). We will show that three results on triangles extend to affine regular polygons.
