A point that represents the average position of all the points in a shape or object, often used in geometry and physics to find the center of mass.

Example

In a triangle, the centroid is the point where all three medians intersect.

I was studying geometry, and I came across the term centroid today.

Oh, I remember that! It’s the center of mass for a shape, right?

Exactly! I was trying to understand how to find the centroid of a triangle.

It's pretty simple; you just average the coordinates of the vertices.
