What is formed when two lines intersect?

When two lines intersect, they create angles at the point where they cross each other. The intersection of the lines provides a geometric point that serves as a vertex for the angles formed on either side of the intersection. Each angle measures the amount of rotation needed to go from one line to the other about the intersection point.

While lines, shapes, and vertices can be related to the concept of intersecting lines, they do not accurately describe what specifically occurs at the point of intersection. Lines simply exist as two distinct entities, shapes encompass various multi-sided figures, and vertices are points of intersection or corners of shapes, not the angular measurement formed specifically due to the intersection of two lines. Thus, the creation of angles is the most precise description of what happens when two lines meet.
