" If "a!=b" then the length of common chord of the circles "(x-a)^(2)+(y-b)^(2)=c^(2)" and "(x-b)^(2)+(y-a)^(2)=c^(2)" is "

The length of the common chord of the circles (x-a)^(2)+(y-b)^(2)=c^(2) and (x-b)^(2)+(y-a)^(2)=c^(2) , is

The length of the common chord of the circles (x-a)^(2)+(y-b)^(2)=c^(2) and (x-b)^(2)+(y-a)^(2)=c^(2) , is

The length of the common chord of the circles (x-a)^(2)+(y-b)^(2)=c^(2) and (x-b)^(2)+(y-a)^(2)=c^(2) , is

Show that the length of the common chord of the circles (x-a)^(2) + (y-b)^(2) = c^(2) and (x-b)^(2) + (y-a)^(2) = c^(2) is sqrt(4c^(2) -2(a-b)^(2)) unit.

The length of the common chord of the circles (x-a)^(2)+y^(2)=r^(2) and x^(2)+(y-b)^(2)=r^(2) is

If the circles (x-a)^(2)+(y-b)^(2)=c^(2) and (x-b)^(2)+(y-a)^(2)=c^(2) touch each other, then
