simétrico

Símétrico is a term used to describe a property of objects, figures, or expressions that exhibit a form of balance or correspondence. This balance can manifest in various ways depending on the context. In geometry, a symmetrical figure can be divided into two or more parts that are identical or mirror images of each other. This can occur across a line (reflectional symmetry) or around a point (rotational symmetry). For example, a circle possesses rotational symmetry, as it looks the same regardless of how it is rotated. A human face is often considered to have approximate reflectional symmetry.

Beyond geometry, symmetry can be observed in other fields. In mathematics, an equation or a function can be symmetric if it remains unchanged when certain variables are interchanged or when transformations are applied. For instance, a quadratic equation like x² + y² = r² is symmetric with respect to x and y. In linguistics, a word or phrase can be considered symmetric if it reads the same forwards and backward, such as "level" or "madam." This is known as a palindrome. The concept of symmetry often implies a predictable pattern or an inherent order, contributing to aesthetic appeal or simplifying analysis in various disciplines.
