Parallel Lines Cut by a Transversal

Front

What are Alternate Exterior Angles?

Back

Angles that are on opposite sides of a transversal and outside the two 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 Alternate Interior Angles?

Back

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

Front

What are Same Side Interior Angles?

Back

Angles that are on the same side of the transversal and inside the two lines.

Front

If m∠VUX = 156°, what is m∠SUT?

Back

m∠SUT = 156° (same angle as VUX).

Front

If m∠UXY = 156°, what is m∠VUX?

Back

m∠VUX = 24° (supplementary to UXY).

Front

If m∠5 = 132°, what is m∠6?

Back

m∠6 = 48° (complementary to angle 5).

Front

What is the relationship between Alternate Interior Angles when two parallel lines are cut by a transversal?

Back

They are equal.

Front

What is the relationship between Same Side Interior Angles when two parallel lines are cut by a transversal?

Back

They are supplementary (add up to 180°).

Front

What is the relationship between Corresponding Angles when two parallel lines are cut by a transversal?

Back

They are equal.
