Jack is constructing the circumscribed circle of δabc with just a compass and a straightedge. which step should he take next in completing the construction?
a(construct the perpendicular bisectors of ab and ac by drawing a line through e and f and another through g and h.
b)construct the perpendicular bisector of bc in the same way as those of ab and ac.
c)mark the point of intersection of the angle bisectors of ∠a and ∠c.
d)draw three lines that pass through ab, bc, and ac, and label the point of intersection.
