What type of shapes are defined by clear edges and geometric forms?

The correct answer is geometric shapes, as they are characterized by precise, clear edges and defined geometric forms such as circles, squares, triangles, and polygons. This category of shapes is often associated with mathematical precision and regularity, making them visually distinctive and easy to identify. Geometric shapes are commonly used in various forms of visual art and design because of their ordered and structured nature.

Other types of shapes mentioned, like organic shapes, are typically freeform and lack definitive edges, resembling the irregularity found in nature. Natural shapes also refer to forms found in the environment, which often do not adhere to strict geometric definitions. Two-dimensional shapes, while they can include geometric shapes, do not exclusively refer to them and can also encompass organic forms, thus making them less specific than geometric shapes.
