Question

Write the formula for centroid and prove it?

Answer 1

Centroid of points, A, B and C is (x1+x2+x3)/3, (y1+y2+y3)/3. Centroid is a point where all the three medians of the triangle intersect. So,the centroid of triangle can be found by finding the average of the x-coordinate's value and the average of the y-coordinate's value of all the vertices of the triangle.
