Geometry Semester Exam Review

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.
