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 corresponding angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are equal in measure.

Front

Identify the pair of angles that are alternate exterior angles: Angle 8 and Angle 1, Angle 2 and Angle 6, Angle 7 and Angle 4, Angle 2 and Angle 8.

Back

Angle 8 and Angle 1 are alternate exterior angles.

Front

What is the value of x if angle 1 is 70 degrees and angle 2 is supplementary to angle 1?

Back

x = 110 degrees.

Front

Define alternate interior angles.

Back

Alternate interior angles are pairs of angles that lie between two parallel lines and on opposite sides of the transversal. They are equal in measure.

Front

What is the sum of the measures of supplementary angles?

Back

The sum of the measures of supplementary angles is 180 degrees.

Front

If two angles are complementary, what is the relationship between their measures?

Back

The sum of the measures of complementary angles is 90 degrees.

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position on two parallel lines in relation to a transversal. They are equal in measure.

Front

Identify the angle relationship: Angle 3 and Angle 5 are formed by a transversal intersecting two parallel lines.

Back

Angle 3 and Angle 5 are alternate interior angles.

Front

What is the measure of angle 4 if angle 2 is 110 degrees and they are corresponding angles?

Back

Angle 4 is also 110 degrees.
