The symmetry principle states that the center of mass of a symmetric object lies along the axis of symmetry. This principle simplifies calculations for moments and centers of mass in symmetric regions.

The symmetry principle can significantly reduce the complexity of integration when determining moments and centers of mass.
For an object with bilateral symmetry, its center of mass will lie on the line or plane of symmetry.
In problems involving multiple objects, each object's symmetry must be considered individually to locate the overall center of mass.
The use of symmetry allows one to determine certain coordinates (usually the $x$ or $y$ coordinate) without performing integration.
Common shapes where the symmetry principle is applied include rectangles, circles, and ellipses.
