Julia has determined that CE is perpendicular bisector of AB. The next step of a valid proof would be: B. AC = BC based on the perpendicular bisector theorem.
What is the Perpendicular Bisector Theorem?
The perpendicular bisector theorem states that if a point is located on a segment (perpendicular bisector) that divides another segment into two halves, then it is equidistant from the two endpoints of the segment that is divided.
Thus, since Julia has determined that CE is perpendicular bisector of AB, therefore the next step of a valid proof would be: B. AC = BC based on the perpendicular bisector theorem.
