This is a picture containing 12 kinds of polygons, some of which also could also be considered a star. The main goal of this is to show that the more points a regular polygon or star has, the closer it becomes to being a circle. The circle is in the middle because I like to have it included and because something should be in the middle. There is also a dodecagon in the vector file which is what held the 12 polygons in the proper place.
