Parallel Lines and Transversals

Front

Which angles are alternate exterior?

Back

Angles 2 and 7 are alternate exterior angles.

Front

A line that intersects two parallel lines is called a

Back

Transversal.

Front

What are alternate interior angles?

Back

Alternate interior angles are congruent.

Front

What are corresponding angles?

Back

Corresponding angles are congruent.

Front

What is the sum of supplementary angles?

Back

The sum of supplementary angles is 180 degrees.

Front

What is the relationship between parallel lines and transversals?

Back

When a transversal intersects parallel lines, it creates pairs of congruent and supplementary angles.

Front

Define alternate exterior angles.

Back

Alternate exterior angles are pairs of angles that lie outside the parallel lines and on opposite sides of the transversal.

Front

Define alternate interior angles.

Back

Alternate interior angles are pairs of angles that lie between the parallel lines and on opposite sides of the transversal.

Front

Define corresponding angles.

Back

Corresponding angles are pairs of angles that are in the same position relative to the parallel lines and the transversal.

Front

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

Back

The angles formed are either congruent or supplementary.
