Question

find the centroid of triangle ABC whose vertices are A (-1,0),B(5,-2)&C(8,2)

Answer 1

directly use centroid formula

Answer 2

Answer:

Coordinates of the centroid of triangle ABC = (4,0)

Step-by-step explanation:

Coordinates of vertice A = (-1,0)

Coordinates of vertice B = (5,-2)

Coordinates of vertice C = (8,2)

To find Coordinates of the centroid :

$(\frac{x_1+x_2+x_3}{3},\frac{y_1+y_2+y_3}{3})\\\\\implies (\frac{-1+5+8}{3},\frac{0+(-2)+2}{3})\\\\\implies (4,0)$

Hence, Coordinates of the centroid of triangle ABC = (4,0)
