Symmetrical and beautiful works of art

Symmetrical and beautiful works of art are mainly presented in the form of paper-cutting and painting.

Data expansion:

Symmetry is the regular repetition of the same part of an object. Crystal has symmetry, which is manifested in its appearance, crystal surface, etc., and its edges and corners appear regularly. Crystal is symmetrical because it is different from other objects.

Symmetric equilibrium theory regards the emergence and development of all things in the universe as a dynamic equilibrium process in which things change from asymmetry to symmetry. In the field of social development, symmetrical balance theory regards social development as a dynamic balance process in which the subject is dominant and the subject and object change from asymmetry to symmetry. Subject-oriented, the transformation of subject and object from asymmetry to symmetry is the most fundamental driving force for social development.

In the field of social economy, symmetric equilibrium theory regards social and economic development as a dynamic equilibrium process in which the subject creates value and the subject and object change from asymmetry to symmetry. The transformation of subject and object from asymmetry to symmetry, which is dominated by the activity of subject creating value, is the most fundamental driving force for social and economic development. Symmetry balance theory regards symmetry as a dynamic nonlinear process and a concrete reflection of the essence of objective things.

Central symmetry and central symmetry figure are two different but closely related concepts. The difference between them is that central symmetry refers to the mutual positional relationship between two congruent figures. They are symmetrical about a point, which is the center of symmetry, and the symmetry of two figures about a point is also called central symmetry.

In two graphs with central symmetry, the symmetry points of all points on one graph are on the other graph, and the symmetry points of all points on the other graph are on this graph; A centrosymmetric figure means that the figure itself is centrosymmetric, and all points on the centrosymmetric figure are symmetrical about the symmetry center on the figure itself.

If two centrally symmetric figures are regarded as a whole (a figure), then this figure is a centrally symmetric figure; A figure with a symmetrical center, if the symmetrical parts are regarded as two figures, then they are symmetrical about the center.
