Construct the perpendicular bisectors. I have added the perpendicular bisector tool.
Drag a corner of the triangle. The intersection of the three perpendicular bisectors is called the circumcenter.Is it possible for the circumcenter to be outside the triangle? If so, describe the triangle.
Is it possible for the circumcenter to be on a side of the triangle? If so, describe the triangle and the position of the circumcenter.
