Regular polygons and their geometric star figures. Regular star polygons with 3 up to 12 sides. Triangle and square, pentagram and hexagram, octagrams and enneagrams, up to 12-pointed dodecagrams.
Nine-pointed geometric star polygon that can be drawn with nine straight strokes. Also called nonagram. Illustration looks three-dimensional.
Regular star polygons, geometric figures, derived from polygons of 4 up to 12 vertices. They consist of triangles, squares, pentagons, hexagons and digons. Some can be connected without interruption.
Geometric star figures derived from convex regular polygons. Regular star polygons with 3 up to 12 sides, from a triangle and square, to a pentagram and hexagram, then to octagrams and enneagrams etc.
