Geometric shapes are characterized by which of the following?

Geometric shapes are defined by their clear, defined boundaries and often possess symmetry. These shapes are usually characterized by specific mathematical properties and can be described with formulas, making them distinct from organic forms. Examples of geometric shapes include circles, triangles, squares, and rectangles, all of which have defined measurements and angles, allowing for predictability and precision in their structure.

In contrast, options suggesting irregular boundaries, organic curves, or soft edges pertain more to organic shapes, which are flexible and often lack the definitive characteristics found in geometric shapes. This distinction is crucial for understanding the foundational differences in visual art, as geometric shapes play significant roles in composition, perspective, and structure within various artistic mediums.
