Centroid Calculator
Compute centroid coordinates for a triangle, an N-sided polygon (shoelace formula), or any set of points.
Choose Triangle, N-sided polygon, or N points mode and enter Cartesian coordinates for each point.
Triangle and N-points modes compute centroid as the arithmetic mean of x and y coordinates.
N-sided polygon mode uses the signed-area (shoelace) centroid formulas and requires vertices ordered around the polygon boundary.
Find centroid of a triangle, an N-sided polygon, or an N-point set. For polygon mode, enter vertices in order around the boundary.
