Angle Relationships

Front

What are corresponding angles?

Back

Angles that are in the same position on different parallel lines cut by a transversal. They are equal in measure.

Front

What are vertical angles?

Back

Angles that are opposite each other when two lines intersect. They are equal in measure.

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the two parallel lines. They are equal in measure.

Front

What are alternate exterior angles?

Back

Angles that are on opposite sides of the transversal and outside the two parallel lines. They are equal in measure.

Front

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

Back

They are equal.

Front

If angle 1 is 67 degrees, what is the measure of angle 5 if they are corresponding angles?

Back

67 degrees.

Front

If angle 6 and angle 7 are vertical angles, and angle 6 is 113 degrees, what is the measure of angle 7?

Back

113 degrees.

Front

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

Back

They are equal.

Front

If angle 3 is 23 degrees, what is the measure of angle 4 if they are vertical angles?

Back

23 degrees.

Front

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

Back

180 degrees.
