Question

What is a line called that intersects two parallel lines?

Answer 1

Hi!

When a line intersects two parallel lines, it is called a TRANSVERSAL LINE.

Also, they form two pairs of vertical angles.

Answer 2

A line that intersects two parallel lines is called a transversal line.

• A transversal line intersects the two parallel lines at two distinct points.
• When a transversal line intersects a pair of parallel lines, then corresponding angles are equal.
• When a transversal line intersects a pair of parallel lines, then alternate angles are equal.
• When a transversal line intersects a pair of parallel lines, then the sum of co-interior angles is 180°.
• The pair of vertically opposite angles are equal.

Hence, a line that intersects two parallel lines is called a transversal line.
