there is a circle say S(adsbygoogle = window.adsbygoogle || []).push({}); _{1},there is a pointPoutside circle. Two tangents are drawn from the pointPto the circle. These two tangents touches circles S_{1}atQandR. A circle is made through P,Q,R. proof that circle is passing through center of S_{1}.

I have tried to put some triangles congruent similar and some other ideas but all failed.
