Page1/1            3 equidistant points on a circle 2010-06-21 From Brian:We have to line up 3 pins on a lifting bridle to be 120 degrees apart from each other to connect into a lifting assembly. 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.     3 equidistant points 2008-12-01 From Damien:How do you find 3 equidistant points (C,D,E) on a line between point A(Xa, Ya) and point B(Xb, Yb) so that AC, CD, DE and EB are all equal?Answered by Chris Fisher.
