36wasn't the first one pretty easy to be in a question for the RMO?
well i didn't appear this time
given, BD/DC = BF/FA
so, DF || AC
=> L ADF = L CAD
L BFK + L BDK = 180° which forces FBDK to be cyclic.
=> α = β done..!!
what was the use of ceva's theorem here to prove AD = CD where D is the point
where the line from B meets AC
