Yep. A vertical line segment above A with length ๐‘– is a horizontal line segment to the left that's 1 unit long. So, the diagram needs a "not to scale" caveat like a map projection, but there's nothing actually wrong with it, and the triangle's BC side is 0 units long.

i= โˆš(-1) = imaginary number (1^2) + (โˆš(-1))^2 = 1 - 1 = 0 7

At least, I thought that was the idea in the OP.

Also, for your version, on a number line or Cartesian plane, the distance from -1 to 1 is 2, not 0

Yeah. I cheated. You have to either deliberately misunderstand how to measure vectors or else drop a minus sign for it to work my way.

(Or, from my previous example, you could just frame it as you're getting the hypotenuse by measuring between |AB| and -|AC|๐‘– instead of the way I framed it -- but that makes it more obvious that you're fishing for a particular answer.)

I liked your other reply better, but either way I still have more to learn. ie, I had no idea what the complex plane is.
