Curved shapes are forms that do not have straight edges or corners. They can be found in nature and man-made objects, such as the roundness of a basketball or the smooth outline of a rainbow. These shapes can be simple, like circles, or more complex, like ovals and spirals. Curved shapes are important in various fields, including art, architecture, and mathematics. In art, they can create a sense of flow and movement, while in architecture, they can enhance structural stability. In mathematics, curved shapes are studied in geometry, where they are analyzed for their properties and relationships.
