Artists use the principles of symmetry and asymmetry to create visual balance and interest in their compositions. Symmetry involves creating a balanced and harmonious arrangement by mirroring elements on either side of a central axis, while asymmetry involves creating balance through uneven distribution of elements. Artists may use symmetry to convey a sense of order and stability, while asymmetry can add a dynamic and lively quality to their work. By understanding and manipulating these principles, artists can create compositions that are visually appealing and engaging to the viewer.
