Question

Write a c program to check whether a circle can be drwan through three given points on the cartesian plane.

Answer 1

Given 3 points in the Cartesian plane, how can you find the coordinates of the center of the circle that intersects all three points.

Answer 2

Only one circle can be drawn. It will be unique. That circle will enclose the triangle formed by those points. Yes, those points can form a triangle as they are non collinear.
