have to include irrational hypoteni Re: all possible angles in the world #1633 Correcting Math

I have to backtrack on All Possible Angles, for the Primitive Ptriples do give me a accurate count on the Rational number angles but they fail to give me the count on legs of right triangle rational but hypotenuse as irrational.
So whereas the formula counting angles as N/pi is a formula for when legs and hypotenuse are rational.
But I need to suplement that counting with right triangles having a irrational hypotenuse. I suspect that it will give me the 2/3 missing or more from the N/pi.
So I need to redo that project and hand count 3 by 3, then 4 by 4 then 5 by 5 and those three should give me enough of a pattern. What is different this time is that I will not use half circle compass to eyeball a angle, but rather denote each triangle as say 1,1,sqrt2, or another triangle as 1,3,sqrt10. In this manner I will not get mixed up over whether I repeated an angle.
