Transversal angle pairs

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

Front

What are corresponding angles?

Back

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

Front

What are vertical angles?

Back

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

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

Back

If two parallel lines are cut by a transversal, the corresponding angles are equal.
