Angle Relationships

Front

What are corresponding angles?

Back

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

Front

What are alternate interior angles?

Back

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

Front

What are alternate exterior angles?

Back

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

Front

What are vertical angles?

Back

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

Front

What are supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

If Angle 2 is 45 degrees, what is the measure of Angle 6 if they are corresponding angles?

Back

Angle 6 is also 45 degrees.

Front

What is the relationship between Angle 4 and Angle 8 if they are corresponding angles?

Back

Angle 4 and Angle 8 are congruent.

Front

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

Back

180 degrees.

Front

If two angles are supplementary and one angle measures 65 degrees, what is the measure of the other angle?

Back

115 degrees.

Front

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

Back

They are congruent.
