Back

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

Front

What is the sum of supplementary angles?

Back

180 degrees.

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 exterior angles?

Back

Angles that are outside the two lines cut by a transversal.

Front

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

Back

They are equal.

Back

113 degrees.

Front

What are same-side interior angles?

Back
