Angles and Parallel LInes

Front

What are corresponding angles?

Back

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

Front

What are alternate interior angles?

Back

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

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

Angles that are on the same side of the transversal and inside the two parallel lines. They are supplementary (add up to 180 degrees).

Front

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

Back

They are equal in measure.

Front

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

Back

They are equal in measure.

Front

If angle 2 is 70 degrees, what is the measure of angle 10 if they are corresponding angles?

Back

Angle 10 is also 70 degrees.

Front

If angle 3 is 50 degrees, what is the measure of angle 5 if they are alternate interior angles?

Back

Angle 5 is also 50 degrees.

Front

What is the relationship between consecutive interior angles?

Back

They are supplementary, meaning their measures add up to 180 degrees.

Front

Identify the angle relationship between angle 6 and angle 12 if they are alternate interior angles.

Back

Angle 6 and angle 12 are equal in measure.
