Several ways to prove but let's use one only

Here

  • PQ is the radius of circle Q

  • PQ is the radius of circle P

Hence P and Q circles have same radius

Now

  • PQ=RQ

As both are radius of circle Q

As both are radius of circle P.

Hence as per transitive property

  • PR=QR

Now

  • PQ=QR=PR

Hence
