Parallel Lines & Transversal Practice

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal in measure.

Front

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

Back

Alternate interior angles are equal when two parallel lines are cut by a transversal.

Front

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

Back

Corresponding angles are equal when two parallel lines are cut by a transversal.

Front

Define complementary angles.

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

Define supplementary angles.

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

If angle 1 is 37 degrees, what is the measure of angle 3 if they are vertical angles?

Back

Angle 3 is also 37 degrees because vertical angles are equal.

Front

If angle 1 is 37 degrees and is an alternate interior angle, what is the measure of angle 2?

Back

Angle 2 is also 37 degrees because alternate interior angles are equal.

Front

Solve for x if angle 1 + angle 2 = 180 degrees and angle 1 = 65 degrees.

Back

x = 115 degrees.

Front

What is the measure of angle B if angle A is 60 degrees and they are corresponding angles?

Back

Angle B is also 60 degrees because corresponding angles are equal.

Front

If two angles are adjacent and one measures 55 degrees, what is the measure of the other if they are supplementary?

Back

The other angle measures 125 degrees.
