    The article itself says it's not new.

        “However, this point of view has been increasingly questioned in recent decades, and a few trigonometric proofs of Pythagoras have made the rounds since then. Claims in the media that Johnson and Jackson’s proof is the first trigonometric proof of Pythagoras are overblown, but their proof could well be the most beautiful and simplest trigonometric proof we have seen to date” my understanding from this part is that their general approach is not new (though certainly astonishing for HS students) but their proof is novel.
