(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

Congruent because rotations, reflections, and dilations preserve size and shape
Similar - Translations and reflections create the same shape but different sizes.
