Chapter 4 15.9 pentagram angles


#1

If anyone doesn’t have cad at work to cheat with, the angle in one of those things is 180/sides. I don’t know if “sides” is the right term here but whatever. For instance on a 7 sided thing the angle is 180/7=25.71 or so. So when you’re trying to figure out how far to turn that’s half the answer.
