Alternate angles on the transversal line are equal
If a transversal intersects a pair of lines and the alternate angles are congruent, the lines are parallel.
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.
They are equal corresponding angles and equal alternate angles
Those are "alternate interior" angles. They're always equal.

alternate angles
Yes. Alternate interior and alternate exterior angles are congruent.
alternate interior and alternate exterior angles
Supplementary angles.
A transversal line that cuts through parallel lines creates equal corresponding angles and equal alternate angles
Its diagonals are perpendicular and intersect each other at right angles or 90 degrees with 1 pair of opposite angles equal in size and 1 pair of unequal opposite angles
