Skip to ContentGo to accessibility pageKeyboard shortcuts menu Precalculus 8.1Non-right Triangles: Law of Sines WebWe can use the Law of Sines to solve triangles when we are given two angles and a side (AAS or ASA) or two sides and a non-included angle (SSA). The Law of Cosines, for any triangle ABC is. a 2 = b 2 + c 2 – 2bccos A. b 2 = a 2 + c 2 – 2ac cos B. c 2 = a 2 + b 2 – 2ab cos C. The following diagram shows the Law of Cosines.

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: And it says that: When we divide side a by the sine of angle A it is equal to side b divided by the sine of angle B, and also equal to side c divided by the sine of angle C Sure ... ? Meer weergeven 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 Meer weergeven 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 … Meer weergeven There is one verytricky thing we have to look out for: Two possible answers.
