Problem 131 of 7
Use coordinates to prove segment PN where N(2,2) is a median of triangle P=1, 5, Q=-1, 1, R=5, 3.
Using a hint is okay. It just tells the trainer to give you a little more review.

show endpoint connects vertex to midpoint.
Hidden until you reveal it.
Segment must connect a vertex to the midpoint of the opposite side.
Enter your answer
Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Identify the opposite side to the vertex.
2. Use the midpoint formula on the opposite side endpoints.
3. Show the segment endpoint is that midpoint, so the segment is a median.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Showing only that the segment touches the opposite side.
