Make-Up Parallel Lines Cut by a Transversal

Front

What are complementary angles?

Back

Angles that add up to 90 degrees.

Front

What are supplementary angles?

Back

Angles that add up to 180 degrees.

Front

What is a transversal?

Back

A line that intersects two or more lines at different points.

Front

If angle 2 is 70 degrees, what is the measure of angle 1 if they are supplementary?

Back

110 degrees.

Front

What is the alternate interior angle to angle 3 if angle 3 is 70 degrees?

Back

Angle 5 is the alternate interior angle.

Front

What are vertical angles?

Back

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

Front

What are corresponding angles?

Back

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

Front

If two angles are supplementary and one angle measures 20 degrees, what is the measure of the other angle?

Back

160 degrees.

Front

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

Back

They are equal.

Front

If angle 1 is 45 degrees, what is the measure of its corresponding angle?

Back

45 degrees.
