Math question. explain please??:)

What's the differences of a corresponding angle, and an alternate interior angle??
Can someone explain to me what they are and how they're different?

Thanks!!

corresponding angles are all on the same side of the straight line that crosses between two parallel lines, while alternate interior angles are between the parallels and on opposite sides of the crossing line. (forgot word for the crossing line, yes it has a name) AIA are equal, and Corresponding are equal.
