Parallel Lines

Front

What are parallel lines?

Back

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

Front

What is the measure of corresponding angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are equal.

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 consecutive interior angles when two parallel lines are cut by a transversal?

Back

Consecutive interior angles are supplementary (add up to 180 degrees).

Front

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

Back

Alternate exterior angles are equal.

Front

What is the sum of the interior angles of a triangle?

Back

The sum is always 180 degrees.

Front

If angle 1 is 44 degrees, what is the measure of its corresponding angle?

Back

44 degrees.

Front

What type of angle pair are angle 1 and angle 3 if they are on the same side of the transversal and inside the parallel lines?

Back

Consecutive interior angles.

Front

If angle 3 is 135 degrees, what is the measure of angle 5 if angle 5 is an alternate interior angle to angle 3?

Back

135 degrees.

Front

What is the definition of vertical angles?

Back

Angles that are opposite each other when two lines intersect; they are equal.
