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.

@MathKevin

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".
