What is the middle point of a plane called?

Answer 1

The middle point of a plane is often referred to as the "centroid" or "center." In a geometric context, the centroid is the average position of all points in a shape, while in a Cartesian coordinate system, the center can be defined as the point with coordinates that are the averages of the x and y coordinates of the vertices. In more general terms, it can also be called the "origin" if considering a coordinate plane where the origin is the point (0, 0).
