Is there any other method of finding circle that passes through 3 given points than writting general equation. This method takes up a lot of time.
As far as I know @Chirag_Bansal that's the only method.
One idea is that can the points can be assumed as vertices of a triangle and further try and find the equation of the circumcircle.
@amansinha09 Yes that's nice, but still that will be time consuming, rather than just solving three simultaneous Linear Equations
