Question

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

Answer 1

Answer:

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

Step-by-step 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''

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