Find the equation of the plane passing through the points. Note that three points can uniquely determine a circle. You can define a plane using the 3 points of a triangle and then the problem is back into R^2 for which you already know the method. The circumcenter of a triangle is defined as the point where the perpendicular bisectorsof the sides of that particular triangle intersects. You find the circumcenter by first finding the midpoint of all three sides of the triangle and then creating a line perpendicular from the midpoint. Then, the distances to O. from the vertices are all equal, we have AO = BO = CO = Circumradius. For an obtuse-angled triangle, the circumcenter lies outside the triangle. First of all, you need to make sure that points are not collinear. Extend the perpendicular bisectors until they intersect each other. ( Using distance formula of two points in a coordinate), By solving these two linear equations using a substitution or elimination method, the coordinates of the circumcenter O (, Since the distances to the circumcenter O, ​Similarly, from the second equality, we have BO, Q.2.
