Parallel Lines Cut by a Transversal

Front

Which of these angles is NOT congruent to angle 5?

Back

Angle 6 is NOT congruent to angle 5.

Front

A line that passes through parallel lines is called a ______________.

Back

transversal.

Front

Name the angle relationship when two angles are opposite each other and formed by two intersecting lines.

Back

Vertical Angles.

Front

If angle 1 is 135 degrees, what is the measure of angle 3?

Back

Angle 3 is also 135 degrees.

Front

If angle 8 is 63 degrees, what is the measure of angle 2?

Back

Angle 2 is 63 degrees because angle 8 & 2 are alternate exterior angles.

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 cut by a transversal.

Front

What is the sum of the interior angles on the same side of a transversal?

Back

The sum is 180 degrees.

Front

If two parallel lines are cut by a transversal, what can be said about the alternate exterior angles?

Back

Alternate exterior angles are congruent.

Front

What is the relationship between same-side interior angles?

Back

Same-side interior angles are supplementary.
