Lines and Angles Review

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

What are alternate interior angles?

Back

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

Front

What are alternate exterior angles?

Back

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

Front

What are consecutive interior angles?

Back

Consecutive interior angles are pairs of angles that are on the same side of the transversal and inside the two parallel lines. They are supplementary, meaning they add up to 180 degrees.

Front

What is the relationship between vertical angles?

Back

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

Front

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

Back

The corresponding angles are equal in measure.

Front

If angle 4 is 70 degrees, what is the measure of angle 6 if lines are parallel?

Back

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

Front

What is the sum of the measures of consecutive interior angles?

Back

The sum of the measures of consecutive interior angles is 180 degrees.

Front

If angle 9 is 120 degrees, what is the measure of angle 16 if lines are parallel?

Back

Angle 16 is 120 degrees because alternate exterior angles are equal.

Front

How do you find the value of x in angle relationships?

Back

Set up an equation based on the angle relationships (e.g., corresponding, alternate interior) and solve for x.
