The following is an incorrect flowchart proving that point L, lying on line LM which is a perpendicular bisector of segment JK, is equidistant from points J and K: Segment JK intersects line LM at point N

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 Side-Angle-Side (SAS) Postulate instead of Angle-Angle-Side (AAS) Postulate.
