The equation of the circle, which is the mirror image of the circle,
As learnt in
Equation of a circle -
- wherein
Circle with centre and radius .
General form of a circle -
- wherein
centre =
radius =
Centre: (1,0) radius = 1
Image of A in the line
x+y=3.
Equation of AB is
x-y=1
Coordinate of C: x+y=3
x-y=1
------------
x=2, y=1
h=3, k=2
Coordinates of B is (3,2) which is mirror image of centre (1,0) and radius is same =1
Hence equation is (x-3)2 + (y-2)2 = 1
x2+y2-6x-4y+12=0
