Law of Sines and Law of Cosines
I can solve a triangle using Law of Sines.
I can solve a triangle using Law of Cosines.
I can solve a real world problem using the Law of Sines and or the Law of Cosines.
The Laws of Sines an Cosines are used in situations where you have a non-right triangle. Each law has its own particular information that is necessary in order to utilize the formula. Both formulas have their issues that make them somewhat more cumbersome to use. They both have issues in that you may have to use found information in order to finish solving the triangle. This would never be allowed in a right triangle situation. Please watch the videos and read the information provided. Each person must have a set of notes that summarizes each video and printed information. The format of your notes is up to you. The quiz over Law of Sines and Law of Cosines is on Tuesday, February 1.
