Only if they add up to 180 degrees which would be the case if the parallel lines are cut through by a perpendicular line.
When a line transverses parallel lines the alternate exterior angles of that line are equal
Alternate and supplementary
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.
yes
They are if parallel lines are cut by a transversal that's perpendicular to them.
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.

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.
they are angles that are usually parallel and that crossed the line that are oppsite from each other
yes
Then the alternate angles created would be equal in size.
They are equal angles as are alternate angles on the transversal line that cuts through parallel lines
They are if parallel lines are cut by a transversal that's perpendicular to them.
The lines are parallel. When a transversal intersects two lines, corresponding angles, alternate interior angles, and alternate exterior angles are congruent only if the lines are parallel. This is a fundamental property of parallel lines and transversals in geometry.
Only if the lines cut by the transversal are parallel.
