Peculiar Stars for my grandchildren Zuzia(5) and Ignaś(3). The stars have 2m + 3 points and the angle between the shoulders is 180 / (2m + 3) and so for m = 1 - pentagrams (5.36) for m = 2 - septagrams (7,180 / 7) for m = 3 - nonagrams (9.20) for m = 4 - hendekagrams (11,180 / 11) for m = 5 - 13-point star polygon (13.180 / 13)
Thanks robiljos000 for the original Peculiar Pentagons project.
