Find the centerpoint of a circle drawn through any 3 points:
Given points p1-3, draw 2 lines: S12 and S23 which each connect two points. From the
midpoint of each line, draw a perpendicular line (S12p/S23p) across the circle. These
lines will cross at the centerpoint.
Mathematically, line S12 will have a slope of m12 which can be determined. Therefore,
the slope m12p is -1/m12. Line S12p will have an equation of y = m12p*x + b12p. b12p can
be solved for using the midpoint of the line. This can be done for both lines. Since
both S12p and S23p cross at the centerpoint, solving the two equations together will give
the location of the centerpoint.
