Interactive video lesson plan for: The Ultimate Transformations Review (Translate, Reflect, Rotate & Dilate)

Activity overview:

This is a review of all transformations including:
1. Translations
2. Line Reflections
3. Point Reflections
4. Rotations about the origin and other points: 90/180/270/360/-450 degrees
5. Dilations about the origin and other points - with scale factors less than 1 and between 0 and 1
6. Glide Reflections
