प्रश्न
Find the centroid of the triangle whosw vertices is (1,4), (-1,1) and (3,2) .
उत्तर
We know that the coordinates of the centroid of a triangle whose vertices are
`(x_1,y_1),(x_2,y_2) (x_3,y_3)`are
`((x_1+x_2+x_3)/3,(y_1+y_2+y_3)/3)`
so, the coordinates of the centroid of a triangle whose vertices are
(1,4),(-1,-1) and (3,-2) are `((1-1+3)/3,(4-1-2)/3)`
`=(1,1/3)`
