In what ways can you describe a translation?

Answer 1

Answer 3

the original figure

Question 4

Image

Answer 4

the resulting figure after undergoing a transformation

Question 5

Answer 8

“slides” every point of the pre-image in the same direction and the same distance to form the image

Question 9

What way do translations face?

Answer 9

the same as the way they started

Question 10

Vector example

Answer 10

<9, 5>

Question 11

Vector

Answer 11

describes translations (how much x and y were shifted); not an ordered pair

Question 12

Rule example

Answer 12

(x, y) -> (x+9, y+5)

Question 13

Rule

Answer 13

creating a rule describes translations clearly by stating how much each direction was slid
