ANSWER

Let P(1, 1), Q(2, -3), R(3, 4) be the mid-points of sides AB, BC and CA respectively of triangle ABC. Let A(x1,y1),B(x2,y2)andC(x3,y3) be the vertices of triangle. ABC. Then,

P is the mid-point of BC

⇒2x1+x2=1,2y1+y2=1

⇒x1+x2=2andy1+y2=2....(i)

Q is the mid-point of BC

⇒2x2+x3=2,2y2+y3=−3

⇒x2+
