Your mistake is not using ordered pairs. Complex numbers are ordered pairs.View attachment 19818
Length = √(i^2+1^2)=√(1-1)=0
How is it possible the length of the hypotenuse to be 0
It isn't! "Length" is always a positive real number, as is "distance", even in the complex plane. In particular, the length of the vertical leg, the distance from 0 to I, is 1, not i.View attachment 19818
