Please help me!:) 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.

Question

anonymous · Answer

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.
