Question

Which rule describes the composition of transformations that maps JKL to J”K”L”

Answer 1

Answer: A

Explanation:

Answer 2

C) Rotate Counter clockwise 90º and Translate (x-2,y)

Explanation:

1) Rotating counterclockwise 90º the
`\bigtriangleup JKL \Rightarrow J'(2,-4), K(5,-4), \:L(2,-2)`

Rotating counterclockwise 90º rule is:
`(-y,x)`

We'll twist the values:

`\bigtriangleup J'K'L' \Rightarrow J(4,2) K(4,5), L(2,2)`

Check the picture below.

2) Now we need to translate ΔJ'K'L' following this rule
`(x-2,y)`

to have ΔJ''K''L''

`\bigtriangleup J''K''L'' \Rightarrow J''(0,2), K''(2,5), \:L''(2,2)`
