  1. 3/21 Geometry Bell Ringer 60° x° What type of triangle is showing? Solve for x Homework: Finish Independent Practice for today.

  2. 3/21 News and Notes • Hand in worksheet from Th/Fri • No MVPs from last week, will combine with this week. • Want to increase your mastery?!: THURSDAY!!!!! • Missing Tests • 1st: None! • 7th: Kaneisha • 8th: None!

  3. Bell Ringer Review • The triangle is a RIGHT TRIANGLE • Today’s Goal: Identify the pieces of right triangles, so that tomorrow we can start TRIGONOMETRY!

  4. Intro to New Material – Vocab (3 min) opp θ θ adj hyp θ

  5. Intro to New Material • Label the opposite leg, adjacent leg, and hypotenuse of the following right triangle with respect to θ: hypotenuse opposite θ adjacent

  6. Intro to New Material • Label the opposite leg, adjacent leg, and hypotenuse of the following right triangle with respect to θ: θ hypotenuse adjacent opposite

  7. 30-60-90 Example Hypotenuse: 2 Opposite: Adjacent: 1 2 θ 1

  8. Guided Practice • Race up your Row!!! • The first person in each column will be in charge of copying down the triangle on paper. • First person labels hypotenuse, second labels adjacent, third labels opposite, fourth writes ratio opp/hyp, fifth writes adj/hyp and raises paper. • Team distractions cost 1 point. • Inappropriate comments cost 1 point. • BONUS FOR REDUCING FRACTIONS!!!

  9. Switch! • First person draws and finds opp. • 2nd labels opposite • 3rd labels adjacent • 4th checks and writes opp/adj • 5th checks and writes opp/hyp

  10. Independent Practice • You now have the rest of class to finish the Independent Practice portion of your guided notes. • EXIT TICKET WITH 5 MINUTES LEFT
