EQUATION OF CIRCLE Definition:         A circle is the locus of a point which moves in a plane in such a way that its distance from a fixed point remains constant.   The fixed point is called the centre of the circle and the constant distance is called the radius of the circle. Equation of the circle with centre (h, k)  and radius ‘r’ units. CP = r                                                                                                                            √(( x – h )2 + (y – k )2   =  r (Using distance formula)  (x – h )2 + (y – k )2…
