1. Glide Reflections and Compositions

2. Vocabulary
Glide Reflection – a transformation that combines a translation and a reflection
as long as the line of reflection is parallel to the direction of the translation, it does not matter whether you glide first and then reflect, or reflect first then glide

7. Vocabulary
Composition – two or more transformations are combined to produce a single transformation
