Angle Relationships When Parallel Lines are Cut by a Transve

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the two parallel lines.

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect. They are equal in measure.

Front

What are corresponding angles?

Back

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

Front

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

Back

They are equal in measure.

Front

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

Back

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

Front

Identify a pair of alternate interior angles in a diagram with two parallel lines cut by a transversal.

Back

For example, angles 3 and 6 are alternate interior angles.

Front

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

Back

Corresponding angles are equal.

Front

If angle 2 is 70 degrees, what is the measure of angle 6?

Back

Angle 6 is also 70 degrees because they are corresponding angles.

Front

What is the sum of the measures of angle 3 and angle 5?

Back

The sum is 180 degrees because they are supplementary angles.

Front

How can you identify vertical angles in a diagram?

Back

Vertical angles are formed by two intersecting lines and are opposite each other.
