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.

The arrow between ΔJNL ≅ ΔKNL and segment J L is congruent to segment K L points in the wrong direction.

Segments JL and KL need to be constructed using a straightedge.

Triangles JNL and KNL are congruent by the Angle-Angle Side (AAS) Postulate.
