(x+5,y)
(x,y-5)
(x-5,y)
(x,y+5)
(-y,x)
(y,-x)
(x,-y)
(-x,y)
(x-3)
(x+3)
(1/3x,1/3y)
(3x,3y)
The correct answer is
(x-3,y-2)
(x+3,y-1)
(x-3,y+1)
(x+3,y+1)
(3x,3y) followed by (x+1,y-2)
(x+2,y-2) followed by a 180 degree rotaiton
Rotate (y,-x) followed by (x+1,y-2)
(-y,x) followed by (-x,y)
Why is your previous answer similar and not congruent?
Dilations create similar images
Rotations create similar images
Reflection create similar images
Translations create similar images

(1,-8)
(7,-8)
(-7,-8)
(-7,8)
(-6,12)
(6,-12)
(6,12)
(-6,-12)
Congruent because rotations, reflections, and dilations preserve size and shape
Similar - Translations and reflections create the same shape but different sizes.
