On January 4th, 2010 Structure says:

Incenter is the intersection of angle bisectors. If it is the same as the circumcenter, intersection of perpendicular bisectors then the triangle is equilateral
Angle bisectot foot D have to be the same as the midpoint of BC and A must be on perpendicular bisector of side BC. Try to drag point A on it! Point D will migrate towards point E
