Angle Relationships

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 are vertical angles?

Back

Angles that are opposite each other when two lines intersect; they are always equal.

Front

What are alternate exterior angles?

Back

Angles that lie outside two parallel lines and on opposite sides of a transversal.

Front

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

Back

They are equal.

Front

If angle 1 is 50 degrees, what is the measure of angle 5 if they are corresponding angles?

Back

Angle 5 is also 50 degrees.

Front

If angle 3 is 70 degrees, what is the measure of angle 6 if they are alternate interior angles?

Back

Angle 6 is also 70 degrees.

Front

What is the relationship between vertical angles?

Back

Vertical angles are always equal.

Front

If angle 4 is 120 degrees, what is the measure of angle 7 if they are vertical angles?

Back

Angle 7 is also 120 degrees.

Front

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

Back

180 degrees.
