Angles and transversals

Front

What are alternate exterior angles?

Back

Angles that are on opposite sides of a transversal and outside the two lines. If the lines are parallel, alternate exterior angles are equal.

Front

If m∠7 = 115°, what is the measure of ∠2 if they are alternate exterior angles?

Back

115°

Front

What is the measure of ∠5 if two parallel lines are cut by a transversal and ∠5 is 88°?

Back

88°

Front

True or False: ∠6 and ∠4 are vertical angles when two parallel lines are cut by a transversal.

Back

True

Front

What are corresponding angles?

Back

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

Front

If angle P measures 60 degrees, what is the measure of angle C if they are supplementary?

Back

120 degrees

Front

What are vertical angles?

Back

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

Front

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

Back

They are equal.

Front

If two angles are supplementary, what is the sum of their measures?

Back

180 degrees.

Front

What is the measure of angle 3 if angle 1 is 70° and they are corresponding angles?

Back

70°.
