a. alex constructed line cd parallel to line segment ab.
b. alex constructed line cd congruent to segment ab.
c. alex constructed line cd to be the angle bisector of segment ab.
d. alex constructed line cd to be the perpendicular bisector of segment ab.

Explanation:

The construction with a compass and straight - edge where two arcs are drawn above and below the line segment from its endpoints is the standard way to construct a perpendicular bisector. The perpendicular bisector of a line segment is a line that is perpendicular to the segment and divides it into two equal parts.

D. Alex constructed line CD to be the perpendicular bisector of segment AB.
