Question

SOMEONE CHECK MY WORK. I THINK ITS THE LAST ONE
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? (5 points)


JL and KL are equal in length according to the definition of a midpoint.
The arrow between ΔJNL ≅ ΔKNL and 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.

Answer 1

Answer 2

last one i guess.

Answer 3

Why do you think that @lochana

Answer 4

In this option posted in the question, something is missing.

>>The arrow between ΔJNL ≅ ΔKNL and points in the wrong direction.

The arrow between ΔJNL ≅ ΔKNL and ? what? points in the wrong direction. @agevd12

Answer 5

This is not the error: Triangles JNL and KNL are congruent by the Angle-Angle Side (AAS) Postulate.

-------

The triangles are congruent by SAS Postulate as stated on the flow chart.

Answer 6

because given triangles are congruent by SAS postulate. not the AAS.
reasons for congruence
1.NL ≅ NL (common for both triangles)
2.JN ≅ NK(since N is middle point of JK)
3. m>JNL ≅ m>KNL = 90 (since lines are perpendicular to each other)
