We did some more work with the Law of Cosines today, specifically looking at two cases where it is useful: when given two sides and a single angle between them (SAS) and when given three sides but no angles at all (SSS). Note that this second case is exactly what your poster will feature!
- Homework: HW 7.10 – More Law of Cosines (you may skip questions 5 and 6)
- Notes (examples on solving SAS and SSS triangles)
- Lesson Video 1 (Law of Cosines with SAS triangle)
- Lesson Video 2 (Law of Cosines with SSS triangle)
