Question

A(2, - 1), B(1, 2) and C(4, 1) are the vertices of a triangle. The coordinates of the centroid of the triangle will be

Answer 1

Answer:

let G( X,Y ) be the centroid of triangle abc

X= 1/3 ( X1 +X2 + x3)

X= 1/3 ( 2+1+4)

x = 2

Y= (y1 + y2 + y3 )

y = (-1 +2 +1)

y= 2/3

hence, the centroid of tring ( 2 , 2/3 )
