Review 3.1 - -3.2

Front

What are Alternate Interior Angles?

Back

Angles that are on opposite sides of a transversal and inside the two lines it intersects. They are congruent when the lines are parallel.

Front

What are Vertical Angles?

Back

Angles that are opposite each other when two lines intersect. They are always congruent.

Front

What are Corresponding Angles?

Back

Angles that are in the same position on two parallel lines in relation to a transversal. They are congruent.

Front

What are Alternate Exterior Angles?

Back

Angles that are on opposite sides of a transversal and outside the two lines it intersects. They are congruent when the lines are parallel.

Front

What are Supplementary Angles?

Back

Two angles that add up to 180 degrees.

Front

If two lines are parallel, what can be said about the Alternate Interior Angles?

Back

They are congruent.

Front

If two lines are cut by a transversal and the Corresponding Angles are equal, what can be concluded about the lines?

Back

The lines are parallel.

Front

What is the relationship between Vertical Angles?

Back

Vertical angles are always equal.

Front

What is the sum of the angles on a straight line?

Back

180 degrees.

Front

What is the relationship between Alternate Exterior Angles when the lines are parallel?

Back

They are congruent.
