Golden Ratio/Heptadecagon - no ruler, just straight edge & compass
grabcad
I didn't know how to title this one.Technically I took the idea from Numberphile's video, "The Amazing Heptadecagon", but I really ran with it and started doing things outside the video. I got the concept of making shapes with just a straight edge and compass but I didn't have either.However, I had SolidWorks. Here I made the Golden Ratio without any dimensions. I think I'll buy a compass for home just do to this stuff.
