Agenda
- Number talk: Always, Sometimes, Never — round two: sides versus angles
- Random groups — three sides, zero angles, and the sine law refuses to start: now what?
- Consolidate: The Cosine Law — and a decision map for choosing your tool
- Check your understanding: Trig Ratios and Laws Practice
Things to do before our next class
- Journal: draw the decision map your own way — how do you pick the tool before touching a formula?
