I'm trying to draft a golden spiral but I keep finding myself snagged
mid-way through the drawing.
I'll explain my procedure first, leading into the issue i'm having.
I start by creating the largest square of the sequence using inches.
I pick any size to fit within the page i'm working on, anywhere from 4"x4" - 9x9.
Once i've done that I divide the length in half and draw my diagonal line from the midpoint
of the side to one of the corners on the adjacent side.
Then while using a compass pivoting on the midpoint, I create my arc
starting at the corner traveling down to level with the length of the square.
Now, to my understanding i've created the golden rectangle.
So, I then proceed on to creating the second, smaller square by using
the measurement of the length I had just created (the golden mean of the first square)
Now i'm left with two squares, one big and one small and one small golden rectangle.
Using the same method as in creating the second square, I create the third square
within the smaller rectangle, which then leaves me with an even smaller rectangle.
Repeating this pattern once or twice more I hit a point where the rectangle i'm left with
is too narrow to continue on. (It's proportions are outside of being a Golden Rectangle).
