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.
