Transversals

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 alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the two lines.

Front

What are parallel lines?

Back

Two lines that run in the same direction and never intersect.

Front

What are consecutive interior angles?

Back

Angles that are on the same side of the transversal and inside the two lines.

Front

What is the alternate interior angle to angle 3?

Back

Angle 5.

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect.

Front

What are supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

What are alternate exterior angles?

Back

Angles that are on opposite sides of the transversal and outside the two lines.

Front

If two lines are cut by a transversal and the corresponding angles are equal, what can be said about the lines?

Back

The lines are parallel.

Front

If angle C and angle P are consecutive interior angles, what can be said about their measures?

Back

They are supplementary (add up to 180 degrees).
