Angle Relationships When Parallel Lines are Cut by a Transve

Front

What are vertical angles?

Back

Vertical angles are angles that are opposite each other when two lines intersect. They are always congruent (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 in measure.

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

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

Back

The sum of the angles on a straight line is 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 in measure.

Front

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

Back

Consecutive interior angles are supplementary, meaning they add up to 180 degrees.

Front

Identify the angle pair: Angle 2 and Angle 6 when two parallel lines are cut by a transversal.

Back

Angle 2 and Angle 6 are alternate interior angles.

Front

What is the relationship between vertical angles?

Back

Vertical angles are always congruent (equal in measure).

Front

If Angle 4 measures 50 degrees, what is the measure of Angle 7?

Back

Angle 7 also measures 50 degrees because they are vertical angles.

Front

What type of angle pair are Angle 3 and Angle 5?

Back

Angle 3 and Angle 5 are corresponding angles.
