Translation Review

Translations in the Coordinate Plane

Video Introduction

• On the next slide, you will watch a video to review Translations. Remember - tranSLations are SLides. A translation will slide a shape.

• Translations will always maintain the shape and size of the pre-image. A translation produces a congruent shape.

Multiple Choice

What is true about the image and pre-image in a translation?

• The image is smaller than the pre-image

• The image and pre-image are congruent (or the same size)

Multiple Choice

When a figure is translated down what happens?

• The x-coordinate gets smaller (subtract from x)

• The y-coordinate gets smaller (subtract from y)

• The x-coordinate gets larger (add to x)

• The y-coordinate gets larger (add to y)

Multiple Choice

When a figure is translated to the right, what happens?

• The y-coordinate gets smaller (subtract from y)

• The y-coordinate gets larger (add to y)

• The x-coordinate gets smaller (subtract from x)

• The x-coordinate gets larger (add to x)
