Intersecting lines are two or more lines that cross each other at a specific point. This point is called the intersection point. When lines intersect, they create angles, which can be measured in degrees. The angles formed can be classified as acute, right, or obtuse, depending on their measurements. In geometry, intersecting lines are important for understanding various concepts, such as angles, triangles, and polygons. They are often used in real-world applications, including architecture and engineering, to create structures and designs. Understanding how lines intersect helps in solving problems related to shapes and space.
