Question

1. point s lies on op. 11. all three lines share point s. 12. the medians are concurrent. which reason completes the proof for step 6? a. definition of slope b. definition of midsegment c. definition of median d. definition of midpoint

Explanation:

A median of a triangle is a line - segment joining a vertex to the mid - point of the opposite side. If the proof is related to medians being concurrent and step 6 is likely about defining what a median is in the context of the proof. The definition of median is relevant here.

Answer:
