Calculating the Golden Ratio Geometrically

[@DesOwen]

Oh I wish I'd had a maths teacher like Eddie when I was young. Mine used to call you up to the board and pinch your leg just because he could get away with it. I got my own back, went on to get a degree in mathematics and computer science. Brilliant teaching Eddie.

I wish you taught me math in eleventh grade. Good teachers who absolutely love what they teach are an asset like you Woo!

Eddie, please show the geometric extraction of a square root of x → √x
the method where you "add length of 1" to x, then "half‑ing the whole thing" take that "half" as a radius, build the circle and trace a perp. line from the point where you "added length of 1", thus the length of that perp. line to where it intersects with the arc (of the circle) is exactly √x
René Descartes has it in its book on Geometry, but never proved it as a method.
To come up with such solution is beyond genius.

This is what I imagine when I say teaching
