Coordinate Geometry Question 1
Question: If the vertices of a triangle be $ (a,b-c),(b,c-a) $ and $ (c,a-b) $ , then the centroid of the triangle lies
Options:
A) At origin
B) On x-axis
C) On y-axis
D) None of these
Show Answer
Answer:
Correct Answer: B
Solution:
$ x=\frac{a+b+c}{3},y=\frac{b-c+c-a+a-b}{3}=0 $
Hence, centroid lies on x-axis.
