Identify and draw translations.

Objective. Identify and draw translations. A translation is a transformation where all the points of a figure are moved the same distance in the same direction. A translation is an isometry, so the image of a translated figure is congruent to the preimage. Example 1: Identifying Translations.

Translations 3-1D

Translations 3-1D. What is the definition of a translation? What are some uses of translations? Is there a connection between translations and vectors?. Definition. A translation is a transformation that moves all the points in a plane a fixed distance in a given direction (slide).

A composition of transformations is one transformation followed by one or more others.

A composition of transformations is one transformation followed by one or more others. A glide reflection is the composition of a translation and a reflection across a line parallel to the translation vector. Example: Describing Compositions. Workbook pg 392 Practice #1 -2.

Does the transformation appear to be an isometry? Explain.

Translations. LESSON 9-1. Additional Examples. Does the transformation appear to be an isometry? Explain. The image appears to be the same as the preimage, but turned. . Because the figures appear to be congruent, the transformation appears to be an isometry. Quick Check.
