Unit 5: Law of Sines and Cosines
Pg 49-50 Started this unit with the investigations by Illumination that develop the Law of Sines and Cosines. Then we used these pages to practice the formulas.
Pg 53-54 Similar to our Law of Sines pages, we developed the formulas and then practiced the Law of Cosines.
Pg 55-56 We practiced word problems by first using the COS diagram (Thanks Meg Craig!) to decide when to use LoC and when to use LoS.
