Question 1196006
<font color=black size=3>
Choice A is a reflection over the y axis
Choice B is a translation of 6 units to the right and 6 units up
I'll get back to choice C later
Choice D is a 90 degree rotation counterclockwise


Choices A, B and D are rigid transformations. They do not change the size and shape of the figure. 
The preimage and image will be congruent figures.
So we can rule them out.


Choice C describes a dilation. 
The jump from (x,y) to (6x,6y) means the points are 6 times further away from the origin than before. 
Consequently it leads to the image being 6 times larger compared to the preimage.
This size change is enough to conclude congruence has NOT been preserved.


Answer: Choice C
