Assume segment MP is a median. According to the definition of a median, point P is the midpoint of side L N. By the definition of a midpoint NP = LP. This contradicts the given statement. Therefore, segment MP is not a median.

Is the indirect proof logically valid? If so, why? If not, why not?

Yes. Statements are presented in a logical order using the correct theorems.

Yes. The conclusion was used to contradict the assumption.

No. The conclusion was used to contradict the assumption.

No. The progression of the statements is logically inaccurate.

somone please help me out

kinggeorge · Answer

When it says "This contradicts the given statement" what statement are they talking about?

anonymous · Answer

you saw the file that i put up?

kinggeorge · Answer

I see the picture of a triangle you posted.

anonymous · Answer

Given ΔLMN where the length of segment NP is greater than the length of segment LP, the following is an indirect paragraph proof proving segment MP is not a median:

i don't even kno what they talking about bro i suck at geometry

kinggeorge · Answer

Alright. So let's start by eliminating a couple of the possibilities. 

The method of proof is supposed to be an indirect proof. Indirect proofs are almost always of the form of "assume the opposite of the wanted conclusion, and get a contradiction."

This tells us that we can immediately eliminate two of the answer choices. Can you tell me which ones?

anonymous · Answer

we can eliminate C and D ??

kinggeorge · Answer

It would actually be A and D. The other options, B and C, are talking about "contradicting an assumption" which is exactly what an indirect proof is. Options A and D on the other hand are descriptions of direct proofs.

anonymous · Answer

So im thinking is B then correct?

kinggeorge · Answer

B is correct. We've already eliminated A and D, and C doesn't really make sense.

anonymous · Answer

Thanks man I appreciate it

kinggeorge · Answer

No problem.

anonymous · Answer

you think you can help me in 4 more problems im in flvs right and im trying to get this done

kinggeorge · Answer

Sorry, but I've got to get going in a few minutes, so you'll probably want to try and find someone else to help you.
