Parallel Lines & Transversals

Front

What are parallel lines?

Back

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

Front

What is a transversal?

Back

A line that crosses at least two other lines in the same plane.

Front

Define corresponding angles.

Back

Angles that are in the same position at each intersection where a transversal crosses two lines.

Front

What are alternate interior angles?

Back

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

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect.

Front

What are consecutive interior angles?

Back

Angles that are on the same side of the transversal and inside the two lines.

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 A is 70 degrees, what is the measure of its corresponding angle when two parallel lines are cut by a transversal?

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.

Front

If angle 7 measures 115 degrees, what is the measure of angle 2 if they are corresponding angles?

Back

115 degrees.
