Gregory Taylor sends this along, and asks a really great question about the work:
“Look past the problem of the original triangle having no 90 degrees… they know enough to run a (problematic) check on height to investigate ambiguity of sine. Why would they even do that if they thought it was a right triangle?”

Do you have a good way to help students understand the rigor needed in these sort of proofs?
Thanks to Jonathan Newman for the submission.
This is a fun mistake, via Jonathan Newman. Find it, and then explain how you’d help the kid who made it.
