Doesn’t this also imply that i == 1 because CB is zero, 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.

i is at a right angle (pi/2) to 1 by definition.
