The point where two lines meet is called an intersection. In geometry, intersections occur in various contexts involving lines, rays, and segments. When two straight lines cross each other, they form an angle at their intersection point. This concept is critical in many fields, including urban planning, navigation, and design, where understanding interactions between paths or boundaries is essential. Intersections can vary in complexity, from simple crossing points in a plane to multi-dimensional interactions in advanced mathematical contexts. Essentially, intersections are fundamental in geometry and spatial reasoning.
