The following is an incorrect flowchart proving that point l, lying on which is a perpendicular bisector of , is equidistant from points j and k: what is the error in this flowchart? (1 point) jl and kl are equal in length, according to the definition of a midpoint. point l is equidistant from endpoints j and k, not j and n. the arrow between δjnl ≅ δknl and points in the wrong direction. an arrow is missing between the given statement and ∠lnk ≅ ∠lnj.

Final answer:

The error in the flowchart seems to involve a logical or sequencing mistake in proving that L is equidistant from J and K, where either an incorrect arrow direction or a missing arrow is likely the cause.

Step-by-step explanation:

From the description, it appears that the error in the flowchart is related to the incorrect logic or sequence in proving that point L, which lies on a perpendicular bisector, is equidistant from points J and K. Addressing the provided options, the correct logic should be that since L is on the perpendicular bisector of JK, by definition, L must be equidistant from J and K. Therefore, JL and KL should be equal in length. An incorrect direction of an arrow or a missing arrow in the flowchart represents a logical sequencing issue that needs correction in such a proof. The objective is to ensure that each step logically follows from the previous one, ultimately leading to the conclusion that point L is indeed equidistant from J and K.

The error in the flowchart is in option B.

Point L is equidistant from end points J and K ,not J and N.

What is the error in this flowchart?

Based on the flowchart, JL and KL are equal in length, according to the definition of a midpoint.

Also, the arrow between ∆JNL ≅ ∆KNL and line JL ≅ line KL points in the wrong direction.

Then, an arrow is missing between the given statement and ∠LNK ≅ ∠LNJ

Hence, the only error perceived from the flowchart is saying point L is equidistant from end points J and K ,not J and N because J and N are not end points.
