Find Centroid

Determine the geometric center of a 2D shape using formulas.

Subtractive Method

Calculate centroid of complex shapes by subtracting the centroid of a cutout or gap from the overall shape.

Complex Shape

A shape composed of multiple simpler figures (e.g., rectangle, circle)

Centroid of a Rectangle

The center point of a rectangle, located at (width/2, height/2) from the origin (assuming the origin is at the bottom-left corner).
