Parallel Lines Cut By Transversals!

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

What is the supplement angle to 45°?

Back

135°

Front

What is a transversal?

Back

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

Front

What are corresponding angles?

Back

Corresponding angles are angles that are in the same position on different parallel lines cut by a transversal.

Front

What are alternate interior angles?

Back

Alternate interior angles are angles that lie between two lines and on opposite sides of a transversal.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What is the relationship between angle 4 and angle 8 if they are corresponding angles?

Back

Angle 4 and angle 8 are equal in measure.

Front

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

Back

Alternate exterior angles are equal.

Front

What is the measure of an angle that is supplementary to a 70° angle?

Back

110°

Front

What is the relationship of angles on the same side of the transversal?

Back

They are called same-side interior angles and are supplementary.
