%C A132702 From _Bernard Schott_, Apr 17 2022: (Start)
%C A132702 For any triangle ABC, (see Crux Mathematicorum):
%C A132702 (b+c)/A + (c+a)/B + (a+b)/C >= (12/Pi) * s,
%C A132702 b*c/(A*(s-a)) + c*a/(B*(s-b)) + a*b/(C*(s-c)) >= (12/Pi) * s,
%C A132702 where (A,B,C) are the angles (measured in radians), (a,b,c) the side lengths of this triangle and s the semiperimeter.
%C A132702 Equality stands iff triangle ABC is equilateral. (End)
