The vertical distance from (2, 2) to the line y = 1 is 1 unit long. So the vertical distance from the centre of the new circle to the line y = 1 must also be 1 unit long and the x-coordinate of the centre remains unchanged after the reflection. Hence the centre of the new circle is (2, 0).

The radius of the circle remains unchanged after reflection. Hence, the radius of the new circle is also square root 5 units.
