Parallel Lines & Transversals

Front

What are parallel lines?

Back

Two lines that run in the same direction and will never intersect.

Front

What are complementary angles?

Back

Two angles that add up to 90 degrees.

Front

What are supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

What is the value of x if the angles are supplementary and one angle is 160 degrees?

Back

x = 20 degrees.

Front

What is the alternate interior angle to angle 3 if angle 3 is 75 degrees?

Back

Angle 5 is also 75 degrees.

Front

Identify corresponding angles in parallel lines cut by a transversal.

Back

Angles that are in the same position on different parallel lines.

Front

If two angles are vertical angles, what can be said about their measures?

Back

Vertical angles are always equal.

Front

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

Back

180 degrees.

Front

If angle 1 is 45 degrees, what is the measure of angle 2 if they are corresponding angles?

Back

Angle 2 is also 45 degrees.

Front

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

Back

Alternate exterior angles are equal.
