(When I first clicked the link I noticed it was about mathematical degeneracy as a whole instead of degenerate triangles. I started trying to read the entire article and, it being overly complicated as it is, couldn’t understand how any of it pertained to the triangle specifically. So I just gave up and googled it, finding this link I wanted there) Tags: Visual edit Mobile edit Mobile web edit Disambiguation links added
