5.
 
Solution:
 
We know tha the lengths of tangents drawn from an external point to a circle are equal.
 
→ DR = DS  .. (i)
    CR = CQ  .. (ii)
    AP = AS   .. (iii)
    BP = BQ   .. (iv)
Adding (i), (ii), (iii) and (iv), we get
DR + CR + AP + BP = DS + AS + CQ + BQ
→ DC + AB = DA + BC
 
Hence proved.
