AG 3 Unit 3Parallel lines cut by a Transversal

Front

What are alternate exterior angles?

Back

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

Front

Identify the relationship between angle 2 and angle 6 if angle 2 is 127 degrees.

Back

They are alternate interior angles.

Front

What are vertical angles?

Back

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

Front

If angle 6 is 25 degrees, what is the measure of angle 7?

Back

Angle 7 is 155 degrees.

Front

What is the measure of angle C if it is given as 116 degrees?

Back

∠C = 116°.

Front

Define corresponding angles.

Back

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

Front

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

Back

180 degrees.

Front

If two angles are supplementary, what is their relationship?

Back

Their measures add up to 180 degrees.

Front

What is the relationship between angle 1 and angle 8 if they are alternate exterior angles?

Back

They are equal.

Front

How do you find the measure of an angle if you know its corresponding angle?

Back

The measure of the corresponding angle is equal to the angle in question.
