Angle Relationships

Front

What are corresponding angles?

Back

Angles that lie on the same side of the transversal and in corresponding positions.

Front

If m∠1 = 50°, what is m∠2 if they are supplementary?

Back

m∠2 = 130°

Front

What is the relationship between alternate interior angles?

Back

They are equal when two parallel lines are cut by a transversal.

Front

If m∠3 = 60°, what is m∠4 if they are vertical angles?

Back

m∠4 = 60°.

Front

Define supplementary angles.

Back

Two angles that add up to 180°.

Front

If m∠5 = 120°, what is m∠6 if they are a linear pair?

Back

m∠6 = 60°.

Front

What are alternate exterior angles?

Back

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

Front

If m∠7 = 30°, what is m∠8 if they are corresponding angles?

Back

m∠8 = 30°.

Front

What is the sum of angles in a triangle?
