Bounded region

Definition

A bounded region is a specific area in a geometric space that is enclosed or limited by boundaries, such as lines or curves. In arrangements of lines, a bounded region is formed when multiple lines intersect, creating finite areas that are confined within certain limits. Understanding bounded regions helps in analyzing geometric properties, calculating areas, and solving optimization problems.
