Vocab Unit #3 Transversals and Angles

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of a transversal and inside the two lines.

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines in relation to 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 supplementary angles?

Back

Two angles that add up to 180 degrees.

Front

What are complementary angles?

Back

Two angles that add up to 90 degrees.

Front

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

Back

They are equal.

Front

If angle 1 and angle 3 are vertical angles, what can be said about their measures?

Back

They are equal.

Front

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

Back

They are equal.

Front

Identify the angle pair: Angle 3 and Angle 6 when two parallel lines are cut by a transversal.

Back

Alternate interior angles.

Front

Identify the angle pair: Angle 7 and Angle 8 when two parallel lines are cut by a transversal.

Back

Corresponding angles.
