d between the tripod legs of angle a Let a be the length of BC, likewise b and c are the lengths of AC and AB. Restricting attention to the plane LBC, consider the locus of points L' arrived at by sliding the tripod and maintaining contacts at B and C Remembering that in a circle, a chord subtends… … And the perpendicular bisector of a chord passes thru the center of the chord's circle bisecting the central angle. Let S be the distance between the center of the circle and the chord BC So by trigonometric definitions: R « a / 2sin(«) S ■ R eos(a) 105 •
