VocabularyAs you can see in the image to the left, there are some terms and some terminology you need to know.
Congruent means that two angles are the same shape and size. Corresponding means that the angles are "in the same place." Alternate means on opposite sides. Alternate angles are on the opposite sides of a line. Exterior angles are angles that are on the "outside" of two parallel lines. If you are thinking train tracks, they would be angles that are outside the tracks, meaning the train would not "run over them." Interior angles are angles that are "inside" of two parallel lines. They would be in between the train tracks. Finally, vertical angles are angles that would be "across" from each other when two lines intersect. They would be on opposite sides of the X that is formed. 
A couple videos that can help to explain this standard.
