Centroid

A centroid is a point that represents the center of an object or shape, like the balance point. Imagine placing a stick under a shape so it balances perfectly; the spot where it balances is the centroid. In geometry, it's calculated based on the shape's area or mass distribution, serving as a key reference point for symmetry, balance, and structural analysis. The centroid helps in understanding how shapes behave under forces and is fundamental in fields like engineering, architecture, and design.
