Vocab Unit #3 Transversals and Angles

Front

What are alternate exterior angles?

Back

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

Front

What are alternate interior angles?

Back

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

Front

What are corresponding angles?

Back

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

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect; they are always equal.

Front

What is the sum of supplementary angles?

Back

180 degrees.

Front

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

Back

They are equal.

Front

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

Back

They are equal.

Front

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

Back

They are equal.

Front

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

Back

They are supplementary (add up to 180 degrees).

Front

How can you identify corresponding angles in a transversal situation?

Back

Look for angles that are in the same relative position at each intersection.
