Complete the following proof.

Given two concentric circles with AB tangent to smaller circle at R.

.0 A R B Prove: AR = RB STATEMENT REASON Draw OA, OB Auxiliary lines OR 1 AB It A AOR = It A BOR CPCTE OR = OR OA = OB AR = RB Radius I to tangent reflexive radi of same circles are = HL CPCTE PA = PB AR IRS, BS IRS RA LAP, RB I PB
