What is the best next step in the construction of the perpendicular bisector of AB? O A. Use a straightedge to draw an equilateral triangle by drawing line segments from A and B to the point at the bottom where the two circles intersect. O B. It is not possible to bisect AB with this construction. O C. Use a straightedge to draw an isosceles triangle by first drawing line segments from A to the bottom where the two circle intersect. O D. Use a straightedge to draw an isosceles triangle by first drawing a line segment from B to the lower point where the circles intersect.
