Using only a compass and a straightedge, you are constructing a line perpendicular to AB and passing through a given point, M, on AB. With a compass of set width, you have drawn arcs that intersect AB on each side of Mand marked the two intersection points as Pand Q.
The next step in this construction is to place the compass needle on
A) P and set its width to M
B) M and set its width beyond P
C) P and set its width beyond M
D) M and set its width to half the distance between P and M
