Question

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:

Answer 1

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.

Answer 2

The flowchart says that the triangles are cong by AAS, we see that the triangles are congruent by SAS [side-angle-side] .. So I guess that would be the wrong part!

Answer 3

i think thats right

Answer 4

alright, thanks for ur help
