A:
Answer:The endpoint co-ordinates for the mid-segment of Δ PQR that is parallel to PQ are, (-3.5 , 0.5) (for the midpoint of PR) and (-1 , -0.5) (for the midpoint of QR) respectively.Step-by-step explanation:According to the question, in Δ PQR, the co-ordinates of P, Q and R are,( - 3 , 3) , (2 , 1) and  ( -4 , -2) respectively. Let, S and T be midpoints of PR and QR respectively. Then, the co-ordinates of S and T are, (( -3 -4)/2 , (3 -2)/2) = (-7/2 , 1/2)  = (-3.5 , 0.5)  and,((2-4)/2 ,(1-2)/2) = ( -1, -0.5) respectivelySo, the endpoint co-ordinates for the midsegment of Δ PQR that is parallel to PQ are, (-3.5 , 0.5) (for the midpoint of PR) and (-1 , -0.5) (for the midpoint of QR) respectively.
