What is the first step to construct angle EFG congruent to angle DBC using a compass and straightedge?

Back

Place the compass point at B.

Front

What mistake did Eric make when constructing a perpendicular bisector to segment AB?

Back

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.
