Symmetry Properties

Definition

Symmetry properties refer to the characteristics of a mathematical object that remain invariant under certain transformations, such as rotation, reflection, or translation. These properties help to identify and classify structures based on their geometric configuration, which is essential for understanding complex relationships and configurations in various mathematical contexts.
