Symmetrical designs are visual arrangements where elements are balanced and mirror each other on either side of a central axis. This balance can be found in various forms, such as in architecture, graphic design, and nature. For example, the Parthenon in Greece showcases symmetrical design through its evenly spaced columns and harmonious proportions. In art, symmetrical designs often evoke a sense of order and stability. Artists may use symmetry to create pleasing compositions, as seen in the works of Leonardo da Vinci or M.C. Escher. These designs can enhance aesthetic appeal and draw the viewer's attention to the central focus of the artwork.
