Question

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?

Answer 1

Construct the perpendicular bisectors of AB¯¯¯¯¯ and AC¯¯¯¯¯ by drawing a line through E and F and another through G and H.

Construct the perpendicular bisector of BC¯¯¯¯¯ in the same way as those of AB¯¯¯¯¯ and AC¯¯¯¯¯.

Mark the point of intersection of the angle bisectors of ∠A and ∠C.

Draw three lines that pass through AB¯¯¯¯¯, BC¯¯¯¯¯, and AC¯¯¯¯¯, and label the point of intersection.
