Lines in a plane that never meet and are always the same distance apart.

Front

What is the definition of a transversal?

Back

A line that intersects two or more lines at different points.

Front

If two angles are supplementary, what is the sum of their measures?

Back

180 degrees.

Front

What is the definition of vertical angles?

Back

Angles that are opposite each other when two lines intersect; they are equal.
