Following the steps below, what is the next step in constructing a perpendicular to a segment? 1. Start with a line and point K on that line.

2. Set the compass’s width to a medium setting. The actual width does not matter.

3. Without changing the compass’s width, mark a short arc on the line at each side of the point K, forming the points P and Q. These two points are the same distance from K because you did not change the width of the compass.

4. ?

A. Increase the compass to almost double the width (the exact setting is not important)
B. From P, mark off a short arc above K.
C. Without changing the compass’s width, repeat from the point Q so that the two arcs cross each other, creating the point R.
D. Using the straight edge, draw a line from K to where the arcs cross.
