I just found this old question

https://web2.0calc.com/questions/isosceles-amp-equilateral-triangles-perimeter-and-area

Our guest's answer had been automatically blanked, probably becasue it had a link in it.

This must be the first time a moderator had looked at it.

It is a neat question and answer.

Some of you might like to take a look :)

Thanks for the question Benjamingu22 and thanks guest for leading us to the answer :)

That looks kind of like a Fibonacci Spiral. It is based on the sequence \(t(n)=t(n-1)+t(n-2)\) . Eventually, this will leave you with the constant phi, which equals \(1+\frac{1}{1+\frac{1}{1+\frac{1}{1+\frac{1}{\dots}}}}=\frac{3-\sqrt{5}}{2}\)
