math help please?

Question

Given coordinates P(-2,3)Q(4,5)R(6,-1) if a is the midpointof PR and B is the midpoint of QR then prove that AB is the midsegment of TRIANGLE PQR.

Answer 1

Find the midpoint of PR which is (2, 1) using the midpoint formula
Find the midpoint of QR which is ( 5, 2).
Find the length of AB using the distance formula. SQRT 10
Find the length of QP which is SQRT 40 or 2SQRT 10
That proves it's a midsegment because AB is half of QP
