Which of the following constructions is illustrated?

• The bisector of a given angle

• The bisector of a given segment

• The perpendicular bisector of a given segment.

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.

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

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

Which is the basis for the procedure used in the construction of a line parallel to a given line through a point not on the line?
