P(2,1), Q(11,1), and R(8,7)
M and N are the midpoints of PR and QR respectively.
Find MN and PQ.
How do these lengths compare with each other?.

geometry 
Reiny,
I will find M
x of M is (2+8)/2 = 5
y of M is (1+7)/2 = 4
M is (5,4)
you find N
then use the distance between two points formula to finish the question
