I've been thinking about this for years You can represent the hypotenuse as a series of steps, then just take the limit All the vertical faces should add up the the vertical side, and same with the horizontal. So a+b=c Surely someone else has come up with this 🤔

the issue, in modern mathematical language, is a failure of continuity: in any topology in which that sequence of steps converges to the hypotenuse, the limit of the lengths is not the length of the limits, so length isn't continuous
