Respected sir/madam Please answer my question JKLM is a trapezium where JK is parallel to LM.If the diagonols MK and Jl intersect each other at N, then the value of MK*NL is always eqaul to 1)ML*JK                                 (  * REPRESENTS PRODUCT) 2)MJ*KL 3)MN*JL 4)KM*JL

MK = 2a and JL = 2b
MN = NK and JN = NL as the diagonals bisect each other
Now, MK x NL = 2a x b = 2ab
And, 2ab = 2b x a = JL x MN = MN x JL
Hence, MK x NL = MN x JL
