Parallel Lines & Transversal

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the two parallel lines. They are equal in measure.

Front

What are alternate exterior angles?

Back

Angles that are on opposite sides of the transversal and outside the two parallel lines. They are equal in measure.

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect. They are equal in measure.

Front

What is a linear pair of angles?

Back

A pair of adjacent angles that are formed when two lines intersect. The sum of their measures is 180 degrees.
