What is the best next step in the construction of the perpendicular bisector of
ab?
o
a. it is not possible to bisect ab with this construction.
o
b. use a compass to draw a circle using the lower intersection of the
circles as the center point.
c. use a straightedge to draw a line segment that connects the
vertices of the two equilateral triangles that coincide with the
intersections of the circles.
o
d. use a compass to draw a circle using the upper intersection of the
circles as the center point.
