A) \[\left( 3,\frac{7}{3} \right)\]
B) \[\left( -3,\frac{-7}{3} \right)\]
C) \[\left( 3,\frac{-7}{3} \right)\]
D) \[\left( -3,\frac{7}{3} \right)\]
Correct Answer: A
Solution :
Let PQR be a triangle and A (4, 2), B (3, 3) and C (2, 2) be the mid-points of sides PQ, PR and QR respectively. Now, G is the centroid of triangle PQR. Also, G (x, y) is the centroid of triangle formed by joining A, B and C. \[\therefore \] \[x=\frac{4+3+2}{3}=\frac{9}{3}\] and \[y=\frac{3+2+2}{3}=\frac{7}{3}\] \[\Rightarrow \] \[G=\left( 3,\frac{7}{3} \right)\]You need to login to perform this action.
