What is the error in this flowchart?

JL and KL are equal in length according to the definition of a midpoint.

The arrow between ΔJNL ≅ ΔKNL and segment J L is congruent to segment K L points in the wrong direction.

An arrow is missing between the given statement and ∠LNK ≅ ∠LNJ.

Triangles JNL and KNL are congruent by the Side-Angle Side (SAS) Theorem.
