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:
What is the error in this flowchart?

JL and KL are equal in length, according to the definition of a midpoint.
An arrow is missing between ∠LNK = 90° and ∠LNJ = 90° and ∠LNK ≅ ∠LNJ.
An arrow is missing between the given statement and ∠LNK ≅ ∠LNJ.
Triangles JNL and KNL are congruent by the Angle-Angle Side (AAS) Postulate.
