Okay thanks, I was having an argument with my math teacher over weather or not that triangle was congruent, I did draw that in ms paint though, and those aren't right angles. His argument was that you could move the lines (with 1 dash through it) up and down so the third line wouldn't be the same, I said that if he was to do that they wouldn't cross at the same spot. Hope some of that made sense
