The points P and Q in the following figure define the line segment (PQ⎯⎯⎯⎯⎯) P Q . The steps involved in using a compass to construct the perpendicular bisector of the line segment (dashed line) are listed in random order below. In the spaces provided, list the letters associated with each step, in the correct, logical order to construct the perpendicular bisector of PQ⎯⎯⎯⎯⎯ P Q .
