3/21 Geometry Bell Ringer 1. What type of triangle is showing? 2. Solve for x Homework: Finish Independent Practice for today. 60° x°

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 – 1 st: None! – 7 th: Kaneisha – 8 th: None!

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!

Intro to New Material – Vocab (3 min) Opposite Leg Side across from the given angle. Side next Adjacent Leg to the given angle. Side across Hypotenuse from the right angle. opp θ θ adj hyp θ

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

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

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

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!!!

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

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

ACT Question of the Day – EXIT TICKET! Calculate with respect to θ in the θ following right triangle: 3 A. B. C. D. E. 3/5 3/4 4/3 5/4 5/3 5 4 If you can, write down the trig ratio that we just calculated in this problem.
