Use the diagram below for the following question.
P(2,1), Q(11,1), and R(8,7)
M and N are the midpoints ofandrespectively.
Find MN and PQ.
How do these lengths compare with each other?.

Max,
Which points are M and N the midpoints of?

Reiny,
"M and N are the midpoints ofandrespectively"
From the context of the problem I will assume you meant
"M and N are the midpoints of RP and RQ respectively"
M is (5,4) and N is (9.5 , 4)
MN = √((9.55)^2 + (44)^2) = 4.5
PQ = √((112)^2 + 0^2) = 9
So what do you think?
( I suggest you also check the slopes of MN and PQ )
