A) \[\left( -1,-1 \right)\]
B) \[\left( -2,-2 \right)\]
C) \[\left( 3,\text{ }4 \right)\]
D) \[\left( 4,\text{ }4 \right)\]
Correct Answer: A
Solution :
(a): Centroid of \[\Delta ABC=\left( \frac{{{x}_{1}}+{{x}_{2}}+{{x}_{3}}}{3},\frac{{{y}_{1}}+{{y}_{2}}+{{y}_{3}}}{3} \right)\] \[=\left( \frac{2-4~-1}{3},\frac{-4-2+3}{3} \right)=(-1,-1)\] Hence, \[\left( -1,\text{ }1 \right)\] is the centroid of \[\Delta ABC\]You need to login to perform this action.
