We finished our example from last class and looked at multi-triangles problems.  We have time to do two Ted Ed riddles (the bridge riddles and the passcode riddle).  Students are given practice questions and a worksheet on angles of elevation/depression for practice over the winter break.

Practice: Chapter 3.3 Page 48 # 1, 2, 4, 5, 7

We looked at what it means to "solve a right triangle."  Plus, we discussed angle of elevation and angle of depression.

Announcement:  Test 4 on Trigonometry on Jan 15, 2019 Tuesday during class time.

Puzzle 23: Sequencing Cards

We did some review before the quiz today.  Quiz 3 completed today.  We also went to a holiday celebration at the foods room.

​Puzzle: none due to quiz.

We went over the worksheets from last class and discuss on when to use which trigonometry ratio.  We also introduced what it means to solve a right triangle (finding all missing sides and angles).

Reminder: Quiz next class.

Puzzle 80: Coin Jumping

We looked at multi-steps sine and cosine questions today.  There were a bit of class time left for students to work on 2 worksheets, which we will go over next day.

Announcement: Quiz 3 on trigonometry ratios (sin, cos, tan) on Friday Dec 14th during class time.

​Puzzle 69: Handshakes

We went through the 2 worksheets from last class.  And then, we looked at the Sine and Cosine ratios.  We introduced the acronym "SOH CAH TOA."  We also discussed on how to find the length if the unknown is at the denominator (ie. looking for the hypotenuse in cases of sine and cosine or adjacent in the case of tangent).

Puzzle 70: Milk Crate

We spend time working on two worksheets in class.  The worksheets are based on the tangent ratio (Chapter 3.1).
