Question

Find circumcenter O and choose the squared-distance equality that verifies it is equidistant from A, B and C.

$$A=(17,0),\quad B=(-3,20),\quad C=(-15,-16)$$

Accepted Answer

$$O=(-3,0),\quad (OA^2,OB^2,OC^2)=(400,400,400)$$

Answer

$$O=(-3,0),\quad (OA^2,OB^2,OC^2)=(400,400,401)$$

Answer

$$O=(-3,0),\quad (OA^2,OB^2,OC^2)=(400,401,400)$$

Answer

$$O=(-2,0),\quad (OA^2,OB^2,OC^2)=(400,400,400)$$
