Using "forward by, turn by" you can draw a circle of known circumference, similar to how kids can measure the circumference of a large circle in the sand by counting footsteps. Measuring the diameter is easy - take the ratio and you're done. So "turn by 120" three times makes your "three stick" version. You can go up to 360 sticks by using 1 degree turns ...
I ruled this out because the 'turn' method uses Pi. To discover Pi, we cannot use Pi. That would be a circular argument.
