Multiple Choice

Eric was attempting to construct a perpendicular bisector to the segment AB with a compass and straight edge. Which of the below statements explains what Eric may have done wrong?

• Eric should have started by putting the compass needle point at the midpoint of the segment AB.

• On the second step, Eric should have placed the compass needle point where the first arc intersected the segment AB.

• Eric just needed to open the compass more to create arcs that have a radius of more than half the length of the segment AB.

• Eric didn’t do anything wrong he just needs to connect the opposite endpoints of each arc to finish the construction.
