Shape, or form, refers to the external outline or configuration of an object. It can be two-dimensional, like a circle or square, or three-dimensional, like a cube or sphere. Shapes are defined by their boundaries and can be geometric, such as triangles and rectangles, or organic, resembling natural forms like leaves or clouds. In art and design, shape plays a crucial role in composition and visual interest. Artists use shapes to create balance, contrast, and harmony in their work. Understanding shape helps in recognizing patterns and structures in various fields, including architecture, graphic design, and even nature.
