  1. Consider rotation anti-clockwise 90° about M,
    then D→C and F→B.
    Thus ΔMDF→ΔMCB and hence congruent.

    The result S₁+S₃=S₂+S₄ then follows.

  2. Tr.s MBC & MFD are congruent SAS hence they are equal in area and the result follows

  3. Problem 1224
    Let area triangle ABC is (ABC).Then (BMC)=(ABM) (BM=MC). But <BMA+<DMF=180 so
    (MDF)/(ABM)=(MF.MD)/(BM.AM)=1.So (BMC)=(MDF) or S_1+(MHPQ)+S_(3 ) =S_2 +(MHPQ)+S_4.
    Therefore S_1+S_(3 )=S_2+S_4.
