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.
What is the greatest number of parts of a circle that can be formed by cutting the circle with 7 straight cuts? (note: the parts do not have to be equal in size)
