Transcript of List of Centroids
The following diagrams depict a list of centroids. A centroid of an object X in n-dimensional space is the intersection of all hyperplanes that divide X into two parts of equal moment about the hyperplane. Informally, it is the "average" of all points of X. For an object of uniform composition (mass, density, etc.) the centroid of a body is also its centre of mass.
