If `S=0,S'=0` are any two non- concentric circles then its radical axis is

Prove that on pair of concentric circles can have a radical axis.

If S = 0, S' =0 are two touching circles then angle between their radical axis and the common tangent at the at their points of contanct is

If S = 0, S' =0 are two touching circles then angle between their radical axis and the common tangent at the at their points of contanct is

Let S and S' be two (non - concentric circles with centres Aand B and radii r_(1),r_(2)and d be the distance between their centres , then one circle lies completely inside the other circle iff

If S = 0, S' =0 are touching circles, then the angle between the line of centres and radical axis of S = 0, S' =0 is

Consider two statements S1 && S2 as s1: Radical Axis is identical to common chord of two circles which are intersecting S2: Radical Axis is locus of all such points such that lengths of tangents drawn from it to two circles are equal

If the circle S=0 touches X -axis then

(a,c) and (b,c) are the centres of two circles whose radical axis is the y-axis.If the radius of the first circle is r then the diameter of the other circle is
