Question

Ryan wants to describe the translation shown on the grid below. Ryan uses the following steps to describe the translation. Step 1: Identify the pre-image and the image: The pre-image is triangle XYZ, and the image is X'Y'Z'. Step 2: Identify the number of units that each point moves horizontally: Each point moves one unit left. Step 3:Identify the number of units that each point moves vertically: Each point moves three units down. Step 4:The translation is one unit left and three units down. In which step did Ryan make the first error? A. Step 1 B. Step 2 C. Step 3 D. Step 4

Answer 1

Option C. Step 3

Explanation:

step 1

Identify the pre-image and the image: The pre-image is triangle XYZ, and the image is X'Y'Z'

The step 1 is correct

step 2

Identify the number of units that each point moves horizontally: Each point moves one unit left.

The step 2 is correct

step 3

Identify the number of units that each point moves vertically: Each point moves three units down

The step 3 is not correct

Each point moves three units up

step 4

The translation is one unit left and three units down

the step 4 is not correct

The translation is one unit left and three units up

therefore

The first error is in the Step 3

Answer 2

All is correct up to Step 3, where the direction should be described as Up instead of Down. C is the best choice.
