Question

what is the student trying to construct?
a segment congruent to a given segment
a segment shorter than a given segment
a segment longer than a given segment
a segment parallel to a given segment

Explanation:

Step1: Analyze construction process

The student is using a compass to copy the length of segment AB to another location starting from point C. This is the process of constructing a segment congruent to a given segment.

Step2: Recall construction concepts

In geometric constructions, when we use a compass - and - straightedge to make a new segment with the same length as a given segment, we are creating a congruent segment.

Answer:

A. A segment congruent to a given segment
