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.
