3.1 Parallel and Transversals

Front

What are parallel lines?

Back

Two lines that run in the same direction and will never intersect.

Front

What are vertical angles?

Back

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

Front

Identify the alternate interior angle to angle 3.

Back

Angle 5.

Front

What are corresponding angles?

Back

Angles that are in the same position on two parallel lines cut by a transversal; they are equal.

Front

What are consecutive interior angles?

Back

Angles that are on the same side of the transversal and inside the two lines; they are supplementary.

Front

What is a transversal?

Back

A line that intersects two or more lines at different points.

Front

What is the relationship between alternate exterior angles?

Back

They are equal when two parallel lines are cut by a transversal.

Front

What are alternate interior angles?

Back

Angles that are on opposite sides of the transversal and inside the two lines; they are equal when the lines are parallel.

Front

If angle A and angle B are corresponding angles, what can be said about their measures?

Back

They are equal.

Front

What is the sum of consecutive interior angles when the lines are parallel?

Back

180 degrees.
