What is a transversal line?

1. A line that runs parallel to another line

2. A line that crosses one other line

3. A line that crosses two or more other lines

4. A line that angles toward the vertical

The correct answer is: A line that crosses two or more other lines

A transversal line is defined as a line that crosses two or more other lines. This concept is particularly significant in geometry, especially when studying the relationships formed by the angles created at the intersections. When a transversal intersects parallel lines, it generates alternate interior angles, corresponding angles, and exterior angles, which are key to various theorems and proofs. Understanding that a transversal can intersect at least two lines is crucial for further exploration of angle relationships and other geometric properties. The ability to identify and work with transversals enhances comprehension of various geometric principles and can be applied in numerous mathematical contexts.
