Take the average of x-coordinates of the three given points

     =  = -1  = -1.667  (rounded).



Take the average of y-coordinates of the three given points

     =  =  = 0.667   (rounded).



Then the coordinates of the centroid are  

     = -1  = -1.667,    =  = 0.667.



In other words, the centroid is the point  

    (,) = (-1.667,0.667).
