**************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
