How do you find the coordinates of the centriod of triangle abc A(-3,-4) B(-5,6) and C (7,4).

Expert Answers

An illustration of the letter 'A' in a speech bubbles

The coordinates of the centroid of a triangle with vertices at `(x_1, y_1)` ,`(x_2, y_2)` and  `(x_3, y_3)` are given by `((x_1+x_2+x_3)/3, (y_1+y_2+y_3)/3)`

For the triangle ABC with vertices A(-3,-4) B(-5,6) and C (7,4) the centroid lies at: `((-3 - 5 + 7)/3, (-4 + 6 + 4)/3)` or `(1/3, 2)`

The centroid of the triangle lies at `(1/3, 2)`
