    Doesn’t this also imply that i == 1 because CB has zero length, forcing AC and AB to be coincident? That sounds like a disproving contradiction to me.

      I think BAC is supposed to be defined as a right-angle, so that AB²+AC²=CB²

      => AB+1²=0²

      => AB = √-1

      => AB = i

        I mean, I see that’s how they would have had to get to i, but it’s not a right triangle.
