Convex is an adjective used in geometry and mathematics to describe a shape or a surface that curves or bulges outward. It refers to the characteristic of being curved or rounded outward like the exterior of a sphere or the outer side of a lens.
In a more precise context, a convex shape or surface is one where any line segment drawn between two points on the shape lies completely within or on the surface. This means that no part of the shape or surface bends inward, giving it a smooth and rounded appearance. A convex shape can be thought of as having no cave-like or concave regions.
Convexity is an important concept in various fields such as architecture, art, engineering, and optimization sciences. For example, in architecture, the use of convex shapes in design can provide increased structural stability and aesthetic appeal. In art, convexity is commonly seen in sculptures and paintings to create depth and volume.
The opposite of convex is concave, which refers to a shape or surface that curves or bulges inward. The distinction between convex and concave shapes plays a significant role in various mathematical and physical applications, including optics, computational geometry, and mathematical optimization.
