Construct a Perpendicular Bisector

Instructions

1. Use the "Compass" tool to create two congruent circles. First, create a circle with radius AB and center A, then create a circle with radius AB and center B.[br][br]2. Place points using the "Point on Figure" tool at each intersection of the two created circles. Call those two point C and D.[br][br]3. Connect the two points C and D using the "Segment" tool.[br][br]4. Call the intersection of segment AB and segment CD point E.
