Their answer to each station will give them a piece of their story (who, doing what, with who, where, when, etc.). Imho the videos (actually there are more of them but they all resort to the same reasoning) about transversals and the ones about the sum of the angles inside a triangle are not consistent because they are circular reasoning : the "sum of angles in a triangle" starts from alleged proof of "angles in parallel lines and transversals", while these video's don't prove anything (it's taken for granted) in a rogorous manner; the only proof is the proof "ad absurdum" in this video, and this assumes a proven "sum of angles in a triangle". When parallel lines are cut by a transversal, there are 4 special types of angles that are formed - corresponding angles, alternate interior angles, alternate exterior angles, and consecutive interior angles. wat abou, Posted 10 years ago.
