Work out triangle centroid instantly with clear inputs, formula shown and shareable results.
The centroid is where the three medians meet and is the triangle's centre of mass. Its coordinates are the plain averages of the three vertex coordinates, and it divides each median in a 2:1 ratio from the vertex.
Centroid
G = ((x₁+x₂+x₃)/3, (y₁+y₂+y₃)/3)
Yes. Unlike the circumcentre or orthocentre, the centroid lies inside every triangle, including obtuse ones.
On each median the centroid sits twice as far from the vertex as from the midpoint of the opposite side.
