Let point of origin is (0,0)
Let A (2,0) and B (-2,0)are the coordinates of tri.
Midpoint between A and B
let third vertex (X, y)
coordinates of centroid or origin
( 0 ,0)= x1+X2 + x3 /3 ,y1 + y2 + y3 /3
= x+2-2 /3, 0+0+y/3
(0,0)=X/3, Y/3
now put coordinates
X/3 =0
X =0
Y/3 =0
y= 0
hence required vertics is (X, y)
(0,0) ans.
