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?

a) jl and kl are equal in length, according to the definition of a midpoint.

b) an arrow is missing between ∠lnk = 90° and ∠lnj = 90° and ∠lnk ≅ ∠lnj.

c) an arrow is missing between the given statement and ∠lnk ≅ ∠lnj.

d) triangles jnl and knl are congruent by the angle-angle side (aas) postulate.
