1. Translations
Section 9-2

2. A translation, or glide, is an isometry that glides all points the same distance in the same direction.

3. If a transformation T maps any point (x, y) to (x + a, y +b), then T is a translation.
Each point glides 10 units
right and 2 units up.
(3, -2)
(-7, -4)

4. Another way to find a translation is to perform a reflection in the first of two parallel lines and then reflect the image in the other parallel line. A transformation made up of successive transformations is called a composition.

5. A glide reflection combines two isometries to produce a new transformation. This new transfomation is itself an isometry. P P’ P”

To lay it on the line.

7. Why did the chicken cross the basketball court to talk with the ref?
