P5: Properties of Parallel lines

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect. They are equal in measure.

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the two parallel lines. They are equal in measure.

Front

What are alternate exterior angles?

Back

Angles that are on opposite sides of the transversal and outside the two parallel lines. They are equal in measure.

Front

If m∠1 = 65°, what is m∠5 if ∠1 and ∠5 are corresponding angles?

Back

m∠5 = 65°.

Front

If m∠2 = 110°, what is m∠6 if ∠2 and ∠6 are corresponding angles?

Back

m∠6 = 110°.

Front

If m∠3 = 56°, what is m∠4 if ∠3 and ∠4 are vertical angles?

Back

m∠4 = 56°.

Front

If m∠5 = 65°, what is m∠4 if ∠4 and ∠5 are alternate interior angles?

Back

m∠4 = 115°.
