Anglebisector
The
above construction illustrates an angle bisector.
Drag
points A and B to change angle ACB. What do you notice about the

Drag
point F to change the radius of the two purple circles. What do
you notice about ray CG?
Move
point H to change the intersection points E and D. At what
point does this construction no longer hold true?
