Law of Sines:
a/SIN(LA) = b/SIN(LB) = c/SIN(LC)
Law of Cosines:
a^2 = b^2 + c^2 - 2*b*c*COS(LA)
b^2 = a^2 + c^2 - 2*a*c*COS(LB)
c^2 = a^2 + b^2 - 2*a*b*COS(LC)
Pythagorean Theorem for Right Triangle:
a^2 + b^2 = c^2
Isoceles Right Triangle:
LA = 45 deg.  ,  LB = 45 deg.  ,  and  LC = 90 deg.
a = b  ,  and  c = SQRT(2)*a
30-60-90 Right Triangle:
LA = 30 deg.  ,  LB = 60 deg.  ,  and  LC = 90 deg.
b = SQRT(3)*a  ,  and  c = 2*a
  or:
LA = 60 deg.  ,  LB = 30 deg.  ,  and  LC = 90 deg.
a = SQRT(3)*b  ,  and  c = 2*b
Area of Triangle:
Area = a*c*SIN(LB)/2 = b*c*SIN(LA)/2 = a*b*SIN(LC)/2
