media type="custom" key="3962905"  Chapters 6.1 and 6.2 concentrate on the Law of Sines and the Law of Cosines, which are used to solve a triangle for all its sides and angles. Both the Law of Sines and the Law of Cosines are used to solve the missing parts of oblique triangles that do not have a given right angle. The Law of Sines is used when two different cases of given information apply, which include: two angles and any side (AAS or ASA) or two sides and an angle opposite of them (SSA). Also with the Law of Sines, there are "ASS", or donkey, problems in which there are two solutions that need to be solved for. Whereas the Law of Cosines can be applied when there are three sides (SSS) given or two sides and their included angle (SAS). At some points the Laws will both be utilized for solving a complete triangle model. __**Objectives:**__  **Page One – Teaching the Lesson (Title, Amy and Vivian)** - 6.1 and 6.2 Summary (Vivian) - Chapter Objectives (Vivian) - Table of Contents (Amy) - Glossary of definitions and formulas (Amy) -Chapter Cheat Sheet (Vivian) - Podcast: An Introduction Explaining What Formula to Use and When (Amy) - Chapter 6.1 Power Point (Law of Sines) &Chapter 6.2 Power Point (Law of Cosines) (Vivian) - Website: Practice some problems on your own!
