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

• Erick should have started with the needle at the midpoint of segment AB

• Erick should have opened his compass to a bigger radius over half the length of segment AB

• On step #2, Erick should have placed the needle where the first arc intersected segment AB

• Erick needs to now connect the opposite arc endpoints with a straight edge to see where they intersect
