A. Construct the perpendicular bisector of AO.
B. Construct the perpendicular bisector of BO.
C. Construct the perpendicular bisector of AB.
D. Draw arcs intersecting the circle a distance of one radius length from A.
E. Draw arcs intersecting the circle a distance of one radius length from B.
F. Draw arcs intersecting the circle a distance of one diameter length from B.
