Transversal Angles

Front

If m∠1 = 121, what is m∠8?

Back

m∠8 = 121 (Corresponding Angles are equal when two parallel lines are cut by a transversal.)

Front

Angles that lie on opposites sides of the transversal and outside of the parallel lines are called...

Back

Alternate Exterior Angles.

Front

Two lines that are beside each other but will never touch are called...

Back

Parallel Lines.

Front

Angles that lie on the same side of the transversal and in corresponding positions are called...

Back

Corresponding Angles.

Front

The sum of the angles is 180 degrees. The angles will form a straight line when they share a vertex. These angles are called...

Back

Supplementary Angles.

Front

What are angles that are opposite each other when two lines intersect?

Back

Vertical Angles.

Front

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

Back

They are equal.

Front

What do you call angles that are on the same side of the transversal and inside the parallel lines?

Back

Alternate Interior Angles.

Front

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

Back

The lines are parallel.

Front

What is the definition of supplementary angles?

Back

Two angles whose sum is 180 degrees.
