You'll find the center point of the circle by finding the intersection of two lines.
Start off by calculating the line equation for two lines pairs say points 1 to 2 and 2 to 3. then the center point is the intersections of the perpendicular bisection of these two lines.
a quick online search has diagrams here http://www.mathopenref.com/const3pointcircle.html
