But, even if so, two dimensional right angle triangles could still exist as abstract concepts, even if they couldn't actually exist in physical space. No?

In exactly the same way that hypercubes exist.

Yes. "Wortfish" would have us believe that we cannot say anything about hypercubes, because we exist in space that is only 3 dimensional. That will come as a surprise to mathematicians, I expect.
