**************THE INCENTER **************************************

CONSTRUCTION OF THE INCENTER 1) Draw three points, A,B,C 2) Draw AB,BC,AC 3) Bisect any two angles and find the intersection, D 4) Draw perpendicular line to line segment AB through D, get E 5) Circle center D with radius E
Additional constructions needed: 1) How to construct an angle bisector, given an angle CAB Assumption: AC and AB < O Circle Center A with radius O, get points two points n, p Circle Center n radius np Circle Center p radius np, get two points q, r Draw qr 2.) How to construct a perpendicular line to a line L through a point K Assumption: OK > KL Circle Center K with radius O, get points two points n, p Circle Center n radius np Circle Center p radius np, get q Draw qK
