WebMar 9, 2024 · Since the law of sines says a / sin A = b / sin B = c / sin C = 2R it's pretty easy to derive! I know a lot of books leave off the "= 2R" part, and some even go so far as to put the sines on top instead of on the bottom. I think the best way to prove the law of sines is to prove that a / sin A = 2R and then by symmetry the rest follows. WebJust think "abc": Area = ½ a b sin C. It is also good to remember that the angle is always between the two known sides, called the "included angle". How Does it Work?
