Thoughts?

OpenStudy (milo123):

not really

OpenStudy (milo123):

b or d maybe

OpenStudy (will.h):

The change from the image to the new image is that the triangle went on a shrank process no?

OpenStudy (will.h):

So it is clearly a dilation where the new image have shrank. That means the scale factor would definitely be 1/3

OpenStudy (will.h):

Not 3

OpenStudy (milo123):

oh oops i read it wrong i thought it was A'B'C' to ABC

OpenStudy (milo123):

A

OpenStudy (princess):

Thank You

OpenStudy (milo123):

for what @princess

OpenStudy (will.h):

Right so let's take this point from the original shape A(-3,3) for a dilation of a scale factor 1/3 would change the coordinates to (-1,1) now if we apply a reflection across the x axis we would get (-1,-1) Which don't match the corresponding point. Let's try reflection across y axis (-1,1) --> (1,1) works so it is C

OpenStudy (milo123):

oooohhhh

OpenStudy (milo123):
