Parallel Lines and Angle Relationships

Front

What are parallel lines?

Back

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

Front

What are alternate exterior angles?

Back

Angles that are on opposite sides of a transversal and outside the two lines.

Front

What are corresponding angles?

Back

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

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of a transversal and inside the two lines.

Front

What are supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

What are vertical angles?

Back

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

Front

If two parallel lines are cut by a transversal, what can be said about the corresponding angles?

Back

They are equal.

Front

If angle 2 and angle 6 are corresponding angles, what can be said about their measures?

Back

They are equal.

Front

If angle 4 is 70 degrees, what is the measure of angle 6 if angle 4 and angle 6 are alternate interior angles?

Back

70 degrees.

Front

What is the relationship between alternate exterior angles when two parallel lines are cut by a transversal?

Back

They are equal.
