axis of symmetry
geometry
Quick Summary
In geometry, an axis of symmetry is a line that divides a figure into two mirror-image halves. If you can fold a shape along this line and the two sides match perfectly, it has an axis of symmetry. This concept is fundamental to understanding geometric shapes and is also observed in nature, contributing to perceptions of beauty and order. Many animals and plants exhibit various forms of symmetry, such as radial or bilateral, which are defined by how their parts are arranged around an axis or a central point.12
