Yup! At the Topeka newspaper we were hammering this out one day and it was when I realized that the green and red (?) triangles look to have identical slopes, they don't, as evidenced that their edge-ratio doesn't remain the same (2/5 vs 3/8). Thick edges make the hypotenuses look linear despite their bulge.
It's a fun little regressive exercise in geometry, though.
