Parallel Lines and Transversals Review

Front

What are alternate interior angles?

Back

Angles that lie between two parallel lines and on opposite sides of a transversal.

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 vertical angles?

Back

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

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

What is the relationship between angle pairs that prove lines are parallel?

Back

If a pair of alternate interior angles are equal or a pair of same-side interior angles are supplementary, the lines are parallel.

Front

If angle 3 and angle 4 are supplementary, what can be concluded about lines j and k?

Back

Lines j and k are parallel.

Front

What is the definition of same-side interior angles?

Back

Angles that lie on the same side of the transversal and between the two lines.

Front

How can you identify corresponding angles?

Back

By their position; they are in matching corners when a transversal crosses two lines.

Front

What is the sum of the measures of supplementary angles?

Back

180 degrees.
