प्रश्न
A(1, 4), B(3, 2) and C(7, 5) are vertices of a triangle ABC. Find the co-ordinates of the centroid of triangle ABC.
उत्तर
Co-ordinates of the centroid -
`x = (x_1 + x_2 + x_3)/3`
= `(1 + 3 + 7)/3`
= `11/3`
`y = (y_1 + y_2 + y_3)/3`
= `(4 + 2 + 5)/3`
= `11/3`
The co-ordinates of the centroid of triangle ABC are `(11/3, 11/3)`.
