Described below are the first three steps for constructing the perpendicular bisector of a line segment. 1. Start with a line PQ. 2. Place the compasses on one end of the line segment. 3. Set the compasses' width and draw an arc above and below the line. Which BEST describes the width required in step 3? A) slightly shorter than one-quarter the length of the line segment B) slightly lomger than one-quarter the length of the line segment C) slightly shorter than one-half the length of the line segment D) slightly longer than one-half the length of the line segment
