given that , 
   L is the midpoint of side AB of ΔABC and N is the point on AC i.e. AN = 2CN .
We have to prove - AM = CN 
    
 Proof , 
  in Δ ANB .
  By using convs. of  midpoint theoram  .
   M is also a midpoint of AN 
 ⇒ AM = MN 
   now , 
 AN = 2CN 
also ,  AM + MN = 2CN 
        AM + AM ( because AM = MN ) = 2 CN 
        2AM = 2  CN 
     .'. AM = CN ( Proved ).................
