Parallel Lines & Transversals

Front

What are Alternate Exterior Angles?

Back

Angles that are on opposite sides of a transversal and outside the two lines.

Front

What is the Corresponding Angle Postulate?

Back

If two parallel lines are cut by a transversal, then each pair of corresponding angles is equal.

Front

Define Alternate Interior Angles.

Back

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

Front

What are Consecutive Interior Angles?

Back

Angles that are on the same side of the transversal and inside the two lines; they are supplementary.

Front

What is the relationship between Vertical Angles?

Back

Vertical angles are equal to each other.

Front

If angle 4 is 60 degrees, what is the measure of angle 8?

Back

Angle 8 is also 60 degrees because they are corresponding angles.

Front

What type of angle pair are ∠1 and ∠3 if they are on the same side of the transversal and inside the lines?

Back

They are Consecutive Interior Angles.

Front

If two parallel lines are cut by a transversal, what can be said about the Alternate Interior Angles?

Back

They are equal.

Front

What is the sum of the measures of Consecutive Interior Angles?

Back

180 degrees.

Front

If angle A is 48 degrees, what is the measure of its corresponding angle?

Back

Angle A's corresponding angle is also 48 degrees.
