3.7a - Parallel Lines and Transversals - Practice

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.

Front

What are alternate exterior angles?

Back

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

Front

What are corresponding angles?

Back

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

Front

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

Back

They are equal.

Front

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

Back

They are equal.

Front

If angle 2 is 30 degrees, what is the measure of angle 8 if they are alternate exterior angles?

Back

30 degrees.

Front

If angle 6 is 53 degrees, what is the measure of angle 15 if they are corresponding angles?

Back

53 degrees.

Front

What is the sum of the interior angles on the same side of the transversal?

Back

They are supplementary, meaning they add up to 180 degrees.

Front

If angle 1 is 70 degrees, what is the measure of angle 7 if they are alternate interior angles?

Back

70 degrees.
