Indirect proof of a squared circle? The new "Pivotal Arc" diagram (animation must be imagined) near the bottom of the Parallel Dimensions PDF file may finally lead to discovery of the geometry which can create (by the Greek rules) the identified scalene triangle.
A few of the given (observations):
- the left side of the scalene triangle (green) has a length equal to the length of one side of a square inscribed in the golden circle.
- the right side of the triangle is always at 135 degrees (or 315); the bottom side at 0 degrees (or 180).
- a circle's diameter of 2 (or 20, 200, etc.) permits easy inspection of the lines and angles.
The dynamics of this diagram (the golden circle is the focus, the circle to be squared):
The chord of the golden circle (green, left side of the scalene triangle) and its related circle are both allowed to pivot at the point at the top left of the diagram. The larger circle (light blue) has a radius equal to the chord's length and identifies the arc upon which these geometric objects rotate. The green chord has a perpendicular line at its midpoint with a length equal to half the chord's length.
The chord and its circle rotate counter clockwise until the end of the perpendicular line touches a point in the geometry which effectively creates the perfect scalene triangle (that squares the golden circle). When that point is reached, the length of the horizontal line (magenta) in the middle of the scalene triangle is equal to half of the length of one side of the circle's square.
This is neither a completed nor formal analysis, but conceptualizes possible construction geometry of this unique scalene triangle.

How to know when the rotation is completed?
The two diagonal red lines at the bottom of the diagram will have the same length
(the red line on the left has a fixed length and the right diagonal green line a fixed angle).
The swing of the arc (lower right quadrant) of the golden circle is the magical key!
Finally ... resolution for this "mantra" which settled in my mind over a year ago: "To square the circle, one must circle the square".
I always thought that it meant drawing a circle around the expected square (an impossibility).
Now I understand that it meant to swing the circle's inscribed square in a circle.
