I  We know the 3 sides (a, b, c)
P=(a+b+c)/2
TAN(A/2)=RACINE((pb)*(pc)/p*(pa))


a/SIN(A)=b/SIN(B)=c/SIN©=2R


S=RACINE(p*(pa)*(pb)*(pc))


II  We know 1 angle and 2 Adjacent sides (b, c, A)
a^2=B^2+C^22*b*c*COSA


TAN(BC)/2=(bc)/(b+c)*COT(A/2)


S=1/2a*b*SIN(C )=abc/4R=rP


A+B+C=200


A=200BC


S=1/2*a^2*SIN(B)*SIN(C)/SIN(B+C)

IV 1 angle and 2 sides (A, a, c)
a/SINA=b/SINB=c/SINC


C=200ASIN(c*SINA/a)


b=aSINB/SIN(B+C)


S=1/2*c^2*(SINA*SINB)/SIN(A+B)
