Triangle ABC is similar to triangle APQ. They have corresponding line segments. Line segment PQ corresponds to BC.
An imaginary number " i " is the squared root of -1, so whenever you square i it's like squaring a squared root. The squared root would cancel and you would be left with just the number under it, that is, the -1.
i ^ 2 = -1
