Parallel Lines

Front

What are parallel lines?

Back

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

Front

What are same side exterior angles?

Back

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

Front

What is the relationship between same side exterior angles?

Back

They are supplementary, meaning their measures add up to 180 degrees.

Front

What are alternate interior angles?

Back

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

Front

What is the relationship between alternate interior angles?

Back

They are equal in measure when the lines are parallel.

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines in relation to a transversal.

Front

What is the relationship between corresponding angles?

Back

They are equal in measure when the lines are parallel.

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect.

Front

What is the relationship between vertical angles?

Back

They are equal in measure.

Front

If angle 3 is 24 degrees, what is the measure of its alternate interior angle?

Back

24 degrees.
