I know pi*d. I know straight lines connecting these points to each other will result in an equilateral triangle. How does one find these points without using a protractor? There must be a formula (formulae) to work this out mathematically. r = 10.5 inches pi*d = 65.9736 3 segments( arcs) = 21.9912 which is the distance along the circumference that the points are from each other.Answered by Penny Nom.
