Corresponding Angles

Front

What is the sum of the measures of two consecutive interior angles when the lines are parallel?

Back

180 degrees (supplementary)

Front

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

Back

They are congruent.

Front

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

Back

They are congruent.

Front

If two angles are supplementary, what does that mean?

Back

Their measures add up to 180 degrees.

Front

How can you determine the measure of an unknown angle when given one angle and its corresponding angle?

Back

The unknown angle is equal to the given angle.

Front

What is the definition of parallel lines?

Back

Lines that never intersect and are always the same distance apart.
