Regarding the previous email. I went back to the main page and then went back to the practice part of Congruency postulates. It gave me the exact question with a very similar triangle that I had last time, but it is different. It was incongruent and I selected "no" and it worked. So clearly some of these questions are working while the first one I ran into did not work at all.
