Question

Find the lengths of the medians RS and PT of a triangle PQR whose vertices are P(6,2),Q(6,3) and R(3,1)

Open in App
Solution

Point S and T are mid points of PQ and QR respectively.
Then coordinate of S=[6,12]
and coordinate of T=[92,2]
Length of median RS=(3)2+(12)2=9+14
RS=374=372unit
Length of median PT=(32)2+(4)2=94+16
PT=732
