    The circumcenter is the intersection of the perpendicular bisectors of the sides. So we need to find the equations of 2 of the perpendicular bisectors and figure out where they intersect. Or you might try a graphical solution.

    The circumcenter is the place where the right bisectors intersect. So you you have to do the following: 1. Determine a midpoint on a line (say AB) 2. Determine an equation for a line perpendicular to AB that passes through that midpoint you found in (1) 3. Repeat steps 1&2 for another bisector 4. If you equate the two equations together (say they are equal) you can then solve for x in order to find out the x value of the intersection point
