To construct a copy of line segment AB using point C as one of the endpoints, Carrie should take the following step:

Using a compass, measure the distance between point A and point B.

After measuring the distance \( AB \), she would then place the compass point on point C and draw an arc to find the other endpoint of the segment, which will be point D, such that \( CD \) is equal to \( AB \).
