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 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 the transversal and inside the two parallel lines.

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect.

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 is 86°, what is the measure of angle 5 if angle 5 is a corresponding angle?

Back

86°.

Front

If angle 1 and angle 4 are vertical angles, what can be said about their measures?

Back

They are equal.

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 2 is 38°, what is the measure of angle 3 if angle 3 is an alternate interior angle?

Back

38°.

Front

What is the sum of the measures of angles on a straight line?

Back

180°.
