Sierra used the following steps to bisect segment AB: Place the compass on point A. Open the compass wider than half the distance of the segment. Swing an arc above and below the segment. Adjust the compass width, place the compass on point B, and swing an arc above and below the segment. Label the intersection of the arcs created above and below segment AB with points C and D. Draw a line from point C to point D. In which step did her error occur? Explain.
