As nouns the difference between centroid and circumcenter

is that centroid is (mathematics|physics) the point at the centre of any shape, sometimes called centre of area or centre of volume for a triangle, the centroid is the point at which the medians intersect the co-ordinates of the centroid are the average (arithmetic mean) of the co-ordinates of all the points of the shape for a shape of uniform density, the centroid coincides with the centre of mass which is also the centre of gravity in a uniform gravitational field while circumcenter is (geometry) the center of a circumcircle (the circle that passes through every vertex of a given triangle or other cyclic polygon).
