I had a math teacher in high school who drew a perfect circle as can be for a free hand circle. He didn't even try to do it. He drew a big circle, about 1.5' in diameter and it just happened to be perfect to the eye. The line connected perfectly with where he started the circle and we measured it and it was all within like 1/16" around. It was amazing. To the eye it was perfect. He drew a box around it with the words "do not erase". It stayed up there on the board for a few weeks. It was awesome!
