Step-by-step explanation:

  1. JK = LM
  2. L is midpoint of JN ⇒ JL = LN = 1/2JN
  3. JK║LM and JN is a transversal ⇒

       ∠KJL and ∠MLN are corresponding angles ⇒

       ∠KJL ≅ ∠MLN

We have two sides and the included angle of ΔJLK congruent to two sides and the included angle of ΔLNM

Therefore ΔJLK ≅ ΔLNM by SAS rule
