Video Introduction

• On the next slide, you will watch an Introduction video to Translations.

• While you watch the video, fill in the Translations Notes in the Unit 4 Notes Section in OneNote!

Try One!

On your Translation Notes, complete the "Try One!" practice problem!

Fill in the Blank

Try One!

**Use this format: (x+a,y+b)

Multiple Select

Try One!

c) Name the coordinates of the image.

Select the correct coordinates for each point in the image. (CHOOSE 3)

• A'(4,1)

• B'(-1,1)

• C'(0,-1)

• D'(5,3)

• A'(-2,1)

Multiple Choice

Which of the following means translation?

• flip

• turn

• slide

• expand

Multiple Choice

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

• The image is larger than the pre-image

• 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)

Multiple Choice

Where would point J' be if you translated point J 5 units to the left and 2 units up?

• (3, -5)

• (-5, 3)

• (-3, 5)

Multiple Choice
