Jada has this idea for bisecting angle ABC. First she draws a circle with center B through A. Then she constructs the perpendicular bisector of AD.
Does Jada's construction work? Explain your reasoning. You may assume that the perpendicular bisector of line segment AD is the set of points equidistant from A and D.
