If Coordinates of a Triangle are : (x₁ , y₁) , (x₂ , y₂) , (x₃ , y₃) , Then :
[tex]\clubsuit\;\;Centroid\;is\;given\;by\; [\frac{x_1 + x_2 + x_3}{3} , \frac{y_1 + y_2 + y_3}{3}][/tex]
Here : x₁ = -3 , x₂ = 1 , x₃ = 5 and y₁ = 1 , y₂ = 6 , y₃ = 2
[tex]\implies Centroid = [(\frac{-3 + 1 + 5}{3}) , (\frac{1 + 6 + 2}{3})][/tex]
[tex]\implies Centroid = [(\frac{3}{3}) , (\frac{9}{3})][/tex]
[tex]\implies Centroid = (1 , 3)[/tex]
