The Law of Sines. The Law of Sines (or Sine Rule) is very useful for solving triangles: a sin A = b sin B = c sin C. It works for any triangle: a, b and c are sides. A, B and C are angles. (Side a faces angle A, side b faces angle B and. side c faces angle C). Zobacz więcej Well, let's do the calculations for a triangle I prepared earlier: The answers are almost the same! (They would be exactlythe same if we used perfect accuracy). So now you can see that: a sin A = b sin B = c sin C Zobacz więcej In the previous example we found an unknown side ... ... but we can also use the Law of Sines to find an unknown angle. In this case it is best to turn the fractions upside down (sin A/a instead of a/sin A, etc): sin … Zobacz więcej There is one verytricky thing we have to look out for: Two possible answers.
