Let A=(0,1) B=(0,0) C=(1,0)
Suppose that f(A) = (0.4,1.8), f(B) = (1,1), and f(C) = (1.8,1.6).
How do we prove that if its not a translate or glide, then its a rotation?
Is it because since glide is a combination of translation and reflection, and this if its not a translation and not a glide, then its also not a reflection. So it has to be a rotation?
