Parallel Lines and Transversals

Front

What are alternate interior angles?

Back

Angles that lie between two parallel lines and on opposite sides of a transversal.

Front

What are alternate exterior angles?

Back

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

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 same-side interior angles?

Back

Angles that lie between two parallel lines and on the same side of a transversal.

Front

If two angles are supplementary, what is the sum of their measures?

Back

180 degrees.

Front

If two angles are congruent, what does that mean?

Back

They have the same measure.
