"Bent" or "curved" refers to a shape that deviates from a straight line, creating an arc or angle. This term is commonly used in geometry to describe lines, surfaces, or objects that are not linear. Curved shapes can be found in nature, such as the arcs of rainbows or the contours of hills. In engineering and design, curves are essential for creating structures that are both functional and aesthetically pleasing. For example, the design of bridges often incorporates curved elements to distribute weight effectively. Additionally, automobiles utilize curved surfaces to improve aerodynamics and enhance visual appeal.
