Law of Sines:
a/SIN(LA) = b/SIN(LB) = c/SIN(LC)
Law of Cosines:
a2 = b2 + c2 - 2*b*c*COS(LA)
b2 = a2 + c2 - 2*a*c*COS(LB)
c2 = a2 + b2 - 2*a*b*COS(LC)
Pythagorean Theorem for Right Triangle:
a2 + b2 = c2
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
