Trig Ratios!

Here are some videos to watch over Trig Ratios. They will explained in more depth next class. Take notes on a blank piece of paper and title it "Trig Ratios."

Introduction to SINE:

Today we are starting the Pythagorean Theorem. It is a handy-dandy formula we use to find the missing side lengths on right triangles. I think you might be familiar with it, so hopefully these videos will help you remember. Watch the following videos and take your own notes. Make sure to write down examples so you can refer to them later. There are short commercials before each video, sorry about this. After you watch the videos please get the worksheet from the substitute and complete. We will grade this on Tuesday, so whatever you don't finish is homework.

After the videos get the worksheet from the substitute and complete it for class on Tuesday. As you answer the questions you should be drawing to complete a face.

Transformations

Here are some videos to watch over transformations: rotation, reflection, and translation. Take notes while you watch them and watch them in order.

Transformations: Isometry

Watch this video and write down the three examples of Isometric transformations and what make them isometric.
Also, give one example transformation that is not isometric and explain why not.

Review of chapter 3 and Introduction to 3.4 Proving Lines Parallel

Watch these 8 videos by clicking the links provided for each one. Don't worry they are all short. There is sound so if you have headphones please use them. If you don't have headphones then just put the sound on low.

The first few video will be a review of angle relationships we have covered in chapter 3. The last two videos will be an introduction to 3.4 Proving Lines Parallel. Please follow the videos and fill in the notes as you progress through all 8 videos.
