A line that intersects two or more lines is called a?

Explanation:
The idea being tested is what we call a transversal: a line that crosses two or more lines. It simply intersects each line at some point, regardless of the angle of crossing. If the lines happen to be parallel, the transversal creates angle relationships that are often explored in geometry. The other terms describe different things: a median is a segment from a triangle’s vertex to the midpoint of the opposite side; a diameter is a line through the center of a circle with endpoints on the circle; an altitude is a line from a vertex perpendicular to the opposite side. These are specific constructs in particular shapes, not just any line that intersects multiple lines.
