Consider the construction below. (image attached.) What should the next step be if you are constructing the perpendicular bisector through point R?
A. Increase the compass to almost double the width to create another line

B. From P, draw a line that crosses the arc below.

C. Without changing the width of the compass, repeat the drawing process from point Q, making the two arcs cross each other at a new point called K.

D. Close the compass and use the straight edge to draw a line from the midpoint of the arc to point R .
