Geometric structures refer to the arrangements and relationships of points, lines, shapes, and spaces in mathematics and art. They can be simple, like triangles and squares, or complex, like polyhedra and fractals. These structures help us understand spatial relationships and are fundamental in fields such as architecture, engineering, and computer graphics. In addition to their mathematical significance, geometric structures are also found in nature, such as the hexagonal patterns of honeycombs and the symmetry of snowflakes. Artists often use geometric shapes to create visually appealing designs, as seen in the works of M.C. Escher and Piet Mondrian.
