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)

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
