   Who knew?! Squared circle geometry speaks CAPTCHA!
(two sets of lines create a U.S. state code, the state
wherein squared circle geometry speaks Captcha)

    Regarding ratios of lines creating state abbreviation:
Values relate to dimensions of the geometric objects;
second letter of state abbreviation created by set
of lines within the highlighted right triangle.
 

  First letter of abbreviation: 
1.7724538509055160272981674833411..  sqrt(Pi)
/ 0.88622692545275801364908374167057..  sqrt(Pi)/2
= 2.0
 

  Second letter (within and including Pythagorean triangle):
1.772453850905516027298167483342..  sqrt(Pi)
/ 1.5707963267948966192313216916398..  Pi/2
= 1.1283791670955125738961589031215..  2(sqrt(1/Pi))
1 / 0.88622692545275801364908374167057..
= 1.1283791670955125738961589031215..  2(sqrt(1/Pi))
 

   Association of ratios in the right triangle:
2.0 / 1.1283791670955125738961589031215..
= 1.772453850905516027298167483342..  sqrt(Pi)
1.0 / 1.1283791670955125738961589031215..
= 0.88622692545275801364908374167057..  sqrt(Pi)/2
