Intersecting lines are lines that cross each other at a point. This point is called the point of intersection. When two lines intersect, they form four angles around the point of intersection. These angles can be classified as vertical, adjacent, complementary, or supplementary based on their relationship with each other.
Key Concepts:
Point of Intersection: The point where two lines cross each other is called the point of intersection.
In the diagram, lines l and m intersect at point P, forming four angles: angle 1, angle 2, angle 3, and angle 4. We can identify the following relationships:
When studying intersecting lines, it's important to understand the different types of angles that are formed and their properties. Here are some key points to remember:
