Polygons in art refer to geometric shapes with three or more sides, such as triangles, squares, and pentagons. Artists often use these shapes to create patterns, structures, and compositions in their work. The use of polygons can add depth and interest, making the artwork visually engaging. Many modern art movements, like Cubism and Geometric Abstraction, prominently feature polygons. Artists such as Pablo Picasso and Kazimir Malevich explored the use of geometric forms to convey complex ideas and emotions. By incorporating polygons, they transformed traditional representations and challenged viewers' perceptions of reality.
