Definition
In Geometry, a transversal is:
“A line that intersects two or more other lines at different points.”
Key characteristics:
It cuts across two or more lines.
It creates multiple angle pairs (like corresponding, alternate interior, alternate exterior, and same-side interior/exterior angles).
If the lines it intersects are parallel, many of those angles have special relationships (like being congruent or supplementary).
Example:
If a line crosses two parallel lines, it is a transversal, and it forms 8 angles at the points of intersection.
