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 angles that are in the same position on two parallel lines cut by a transversal.

What are alternate interior angles?

Back

Alternate interior angles are angles that are on opposite sides of the transversal and inside the two lines.

How do you find the measure of a missing angle when given one angle formed by a transversal?

Back

You can use the relationships between the angles (such as corresponding, alternate interior, or alternate exterior) to find the measure of the missing angle.
