Parallel Lines and 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 intersects two or more lines at different points.

Front

What are corresponding angles?

Back

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

Front

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

Back

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

Front

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

Back

They are equal.

Front

If angle 1 and angle 2 are corresponding angles, what can be said about their measures?

Back

They are equal.

Front

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

Back

They are supplementary.

Front

If angle 3 = 70°, what is the measure of angle 4 if angle 3 and angle 4 are alternate exterior angles?

Back

Angle 4 = 70°.

Front

Find the measure of angle x if angle 5 = 110° and angle x is a corresponding angle to angle 5.

Back

x = 110°.

Front

If angle 6 = 45°, what is the measure of angle 7 if angle 6 and angle 7 are same-side interior angles?

Back

Angle 7 = 135°.
