In the coordinate plane, the points F (-1,1), G (1,2), and H (2,1) lie on a circle with center P. What are the coordinates of point P ? Pick:  A) (0.5,0.5)  B) (1,1)  C) (1,2)  D) (1,-2)  E) (2.5, -2.5)
I thought I need to find the 4th point that would lie on the circle   Hence my answer was D (1,-1)   But the the center of the circle will lie on (0.5,0.5)   (0.5,0.5)
