Angle relationships

Front

What are corresponding angles?

Back

Angles that are in the same position on parallel lines in relation to 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 lines. They are equal in measure when the lines are parallel.

Front

What are alternate exterior angles?

Back

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

Front

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

Back

They are equal.

Front

If m∠1 = 75°, what is m∠2 if ∠1 and ∠2 are vertical angles?

Back

m∠2 = 75°.

Front

If m∠A = 110° and ∠A and ∠B are corresponding angles, what is m∠B?

Back

m∠B = 110°.

Front

If m∠C = 93° and ∠C and ∠D are alternate interior angles, what is m∠D?

Back

m∠D = 93°.

Front

What is the sum of the measures of angles on a straight line?

Back

180°.

Front

What is the relationship between alternate exterior angles when two parallel lines are cut by a transversal?

Back

They are equal.
