WILL GIVE MEDAL

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.

An arrow is missing between ∠LNK = 90° and ∠LNJ = 90° and ∠LNK ≅ ∠LNJ.

An arrow is missing between the given statement and ∠LNK ≅ ∠LNJ.

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

Answer 4

any ideas?

Answer 5

I thought D but I'm terrible at geometry

Answer 6

why AAS?

Answer 7

I'm not sure...? Maybe A?
I'm so bad at Geometry

Answer 8

@jim_thompson5910

Answer 9

does something seem disconnected in that flow chart?

Answer 10

I think the top where it says LN is congruent to LN is weird....

Answer 11

that's a valid statement

Answer 12

it's like saying x = x

Answer 13

it seems redundant, but it's important

Answer 14

So what should I do?

Answer 15

find the box where it is disconnected from the rest

Answer 16

The part that says Definition Of Congruence?

Answer 17

yeah that reasoning is wrong

Answer 18

but I'm looking at another box

Answer 19

The part that says Draw "JL and KL"?

Answer 20

it's a box that has no arrows pointing away from it

Answer 21

it's like an island

Answer 22

LM is a perpendicular Bisector of JK??

Answer 23

@jim_thompson5910

Answer 24

notice how that doesn't point anywhere

Answer 25

it just stops

Answer 26

it's like they mention it, but never use it

Answer 27

So is it A?

Answer 28

why A?

Answer 29

I just think that is the one

Answer 30

any reason why?

Answer 31

Because it says "Midpoint" an the box you were talkin bout says "Bisector"

Answer 32

Or is it B?

Answer 33

but why did I mention that island thing in the flowchart?

Answer 34

the whole point of a flowchart is to connect everything used on it

Answer 35

Now i think it is B

Answer 36

Am I right?

Answer 37

yes I think so too

Answer 38

THANK YOU!!!!!!

Answer 39

It was right!!! @jim_thompson5910
