Transversals

Front

What is a transversal?

Back

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

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in similar positions at each intersection where a transversal crosses two lines.

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

What is the relationship between consecutive interior angles?

Back

Consecutive interior angles are supplementary, meaning their measures add up to 180 degrees.
