It seems that phi or the golden spiral can be derived from both a triangle and a square? Although they must have the ratio from Fibriccani's sequence, how can two totally different shapes, come up with the same spiral? Isn't it truly bizarre. Why and how does this work? And, where can I learn more? beegirl86@hotmail.com if you wish to disperse some information!! Please.

This is possible because Phi is simple the ratio so that a/b=(b+a)/b, when a and b are 2 sides of a shape. And as for the square, i believe you are mistaken. It is only with a rectangle that this is attainable.

I'm sorry for the error in my previous post. It was rather the ratio so that b/a=(b+a)/b.

Yeah, I was mistaken. Mind lapse, it is a rectangle not a square.
