Only if they add up to 180 degrees which would be the case if the parallel lines are cut through by a perpendicular line.

What is the meaning of alternate exterior angles?
When a line transverses parallel lines the alternate exterior angles of that line are equal
What angles are inside parallel lines on a transversal?
Alternate and supplementary
If two lines are cut by a transversal to form pairs of congruent corresponding angles congruent alternate interior angles or congruent alternate exterior angles then what are the lines?
The lines are parallel. The only time you will see correpsonding, alternate interior, and alternate exterior angles is with a parallel transversal line.
What is alternate exterior angles in math terms?
Alternate Exterior Angles are created where a transversal crosses two (usually parallel) lines. Each pair of these angles are outside the parallel lines, and on opposite sides of the transversal.
Can alternate exterior angles exist without parallel lines?
yes
What are the conditions that guarantee parallelism?
Parallel lines are lines that are coplanar (lying on the same plane) and do not intersectwhen cut by a transversal,corresponding angles formed by line n are equal in measure,alternate interior angles are equal in measures,the measures of alternate exterior angles are equal,consecutive interior angles are supplementary,consecutive exterior angles are supplementary.

Uses of parallel lines cut by a transversal?
There's lots of useful things you can discover when parallel lines are cut by a transversal, most of them having to do with angle relationships. Corresponding angles are congruent, alternate interior angles are congruent, same side or consecutive interior angles are supplementary, alternate exterior angles are congruent, and vertical angles are congruent.
What are alternate exterior angles?
they are angles that are usually parallel and that crossed the line that are oppsite from each other
Can alternate exterior angles exist without parallel lines?
yes
If two parallel lines are cut by a transversal then the alternate exterior angles are?
Then the alternate angles created would be equal in size.
Are corresponding angles supplementary or complimentary?
They are equal angles as are alternate angles on the transversal line that cuts through parallel lines
Can alternate interior angles be supplementary?
They are if parallel lines are cut by a transversal that's perpendicular to them.
Are alternate exterior angles congruent?
Only if the lines cut by the transversal are parallel.
