- noun mathematics, physics The
point at thecentre of any shape, sometimes called centre of area or centre of volume. For a triangle, the centroid is the point at which themedians intersect. Theco-ordinates of the centroid are theaverage (arithmetic mean ) of the co-ordinates of all the points of the shape. For a shape of uniform density, the centroid coincides with thecentre of mass which is also thecentre of gravity in a uniform gravitational field.
