Plane symmetry

Plane symmetry, also known as reflectional symmetry or mirror symmetry, is a type of symmetry in which an object is invariant under reflection across a given plane. In simpler terms, if you were to "fold" an object along a plane, the two halves of the object would match perfectly. In mathematical and geometric contexts, a plane of symmetry divides an object into two mirror-image halves. For example, many organic and inorganic shapes possess at least one plane of symmetry.
