Daryl Posted January 1, 2006 Share Posted January 1, 2006 When laying out a right-angle square 3 + 4 = 5 or 9" on one side, 12" on the other with 15" on the long side will make a perfect right angle Thanks to Pyhtorgas' theorem of right-angle triangles (AxA) + (BxB) = (CxC) . When calculating flat iron to go around in a circle: Length of iron = Circumference plus one and one-half times the thickness of the flat iron.
