symmetry
Symmetry is a feature of geometries, systems, equations, and other objects that are actually or conceptually - typically half of the object is the mirror of the other half. In mathematics, if a geometric figure or object is symmetrical, it means that it is a variable invariant, and the term symmetry is also included in this definition. If the two objects are called symmetrical, it means that the shape of one of them is geometrically segmented, and the segmented segment can be reorganized to the other without changing the overall shape, and vice versa. Symmetry can also be found in humans and other animals and other organisms (see the following biological symmetry). In the two-dimensional geometry, the more interesting several major symmetries are equidistant relative to the basic Euclidean space: translation, rotation, mirror and slip mirror. ...
