When I completed this challenge, it said that I failed the final one, I noticed that this was because for the first 6 tests, the function tested is for def similartriangles(...) whereas test 7/7 asks for the output of def similartriangels, this is a typo, and so I had to enter my code twice for different function spellings. I passed all checks after making the change.
