Glide Reflections and Compositions
2
Compositions When two or more transformations are combined to produce a single transformation The composition of 2 (or more) isometries is an isometry.
3
Glide Reflections Combining, a translation with a reflection
If the line of reflection is parallel to the direction of translation, then it does not matter which you do first. Otherwise, order is important.

1. Finding the Image of a Glide Reflection
Use the information below to sketch the image of QRS after a glide reflection. Q(2, –3), R(4, –4), and S(5, –1) Q’’(-2, 2), R’’(-4, 1), & S’’(-5, 4)

2. Finding the Image of a Composition
Perform the following composition on C(2, 0), D(3, 3) C’(2, 0), D’(3, –3) C’’(0, –2), D’’(–3, –3)

3. Finding the Image of a Composition
Perform the Glide Reflection on A(–3, 5). A’(–6, 2) A’’(2, –6)

4. Describing the composition
Rotation of 180° around the origin Reflection across y = 1
