Agenda

  1. Number talk: Always, Sometimes, Never — claims about triangles
  2. Random groups — no right angle in sight: find the missing side anyway
  3. Consolidate: The Sine Law — including the case where two different triangles both fit your facts
  4. Check your understanding — one ambiguous case, both triangles found

Things to do before our next class

  • Journal: how your group discovered the second triangle hiding in the same three facts.
