Since, ABCD is a parallelogram,

AB = CD (i)

BC = AD (ii)

Now, it can be observed that:

DR = DS (tangents on circle from point D)

CR = CQ (tangents on circle from point C)

BP = BQ (tangents on circle from point B)

AP = AS (tangents on circle from point A)

Adding all the above four equations,

DR + CR + BP + AP = DS + CQ + BQ + AS

(DR + CR) + (BP + AP) = (DS + AS) + (CQ + BQ)

CD + AB = AD + BC (iii)

From equation (i) (ii) and (ii):

2AB = 2BC

AB = BC

AB = BC = CD = DA

Hence, ABCD is a rhombus.
