I solved the question. This is the same bug that another user had identified. There is a correct solution, and the system accepts it, but it's not easy to see what the other noncongruent triangle would be in the ambiguous SSA case.
Perhaps we should try to include specific feedback in the SSA case directing students who get stuck to the video Sal made called "More on why SSA is not a postulate". It would solve all of their problems.
Thanks @MathKevin - agree on directing to the specific video. We will add as a trello card unded "minor bugs".
Add hints and use custom answer-type in congruency_postulates
