The center of mass of an object.For a one-dimensional uniform object of length L, the centroid is the midpoint of the line segment.

For a triangle, the centroid is the intersecting point of its three medians.

The centroid of a symmetrical figure is the center of symmetry. For any other irregular shaped two-dimensional object, the centroid is the point where this single support can balance this object. Generally, the centroid of a two- or three-dimensional object is found by using double or triple integrals.
