X1 INCENTER

The Incenter (X1) is the meet of the interior angle bisectors (which I like to call bilines). It is the first point on Clark Kimberling's list of triangle centers at the Enyclopedia of Triangle Centers, from which this Geometer's SKetchpad worksheet is taken. It is important to note that
