  1. 3/17 Bell Ringer θ 2√3 4 What’s the measurement of the hypotenuse? What’s the measurement of the opposite leg? What’s the measurement of the adjacent leg? 2 Homework: SOHCAHTOA Puzzle Grab today’s guided notes from the front of the room!

  2. News and Notes • Perfection Award: 8th Period • Note on what was handed back to you.

  3. 3/17 Agenda • I CAN identify and calculate the trig ratios given all three sides of a right triangle (SOH CAH TOA) • 1. Intro to New Material – Vocabulary • 2. Guided Practice: Races • 3. Puzzle Time • 4. ACT Question of the Day

  4. Intro to New Material (Ex. #1) • Find the three trig ratios for the 30° angle: 30° 2 √3 1

  5. Intro to New Material (Ex. #2) • Find the three trig ratios for the 60° angle: 2 √3 60° 1

  6. sin θ = 3/5 Cos θ = 4/5 tan θ = 3/4 5 3 θ 4 5 3 θ 5 θ 4 3 θ 4

  7. 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 finds missing side (method of choice), second finds sin (SOH), third finds cos (CAH), fourth finds tan (TOA). • Team distractions cost 1 point. • Inappropriate comments cost 1 point.

  8. Independent Practice • Begin working on your SOHCAHTOA puzzle on the back of today’s notes.

  9. ACT Question of the Day In the figure below, what is ? A. sine of angle G only B. cosine of angle G only C. cosine of angle H only D. sine of angle G and cosine of angle H. Homework: SOHCAHTOA Puzzle
