Transversal Angle Relationships Review

Front

What are alternate exterior angles?

Back

Angles that are on opposite sides of a transversal and outside the two lines it intersects.

Front

What are corresponding angles?

Back

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

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect; they are always equal.

Front

What are alternate interior angles?

Back

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

Front

What are supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

What are complementary angles?

Back

Two angles that add up to 90 degrees.

Front

If m∠7 = 115°, what is m∠2 if they are corresponding angles?

Back

m∠2 = 115°.

Front

If m∠1 = 11x - 9° and m∠5 = 7x + 9°, how do you find x?

Back

Set the equations equal to each other and solve for x.

Front

What is the relationship between vertical angles?

Back

Vertical angles are always equal.

Front

If two angles are supplementary and one angle measures 65°, what is the measure of the other angle?

Back

115° (because 180° - 65° = 115°).
