Answer 1

What set of transformations could be applied to rectangle ABCD to create A'B'C'D'?

Rectangle formed by ordered pairs A at negative 4, 2, B at negative 4, 1, C at negative 1, 1, D at negative 1, 2. Second rectangle transformed formed by ordered pairs A prime at negative 4, negative 2, B prime at negative 4, negative 1, C prime at negative 1, negative 1, D prime at negative 1, negative 2.

Reflected over the x-axis and rotated 180°
Reflected over the y-axis and rotated 180°
Reflected over the x-axis and rotated 90° counterclockwise
Reflected over the y-axis and rotated 90° counterclockwise

@TheSmartOne

Answer 3

@brainzonly LOL answer is C

Answer 4

are you sure?

Answer 5

I think it is just reflected over the x-axis.

Answer 6

Think about it again, brainzonly!

Answer 7

I can hear my brain whirring but it's still telling me C...

Answer 8

Well the x- values remain the same ... the y values changes from 1 and 2 to -1 and -2

Answer 9

so that means it moves across the y-axis to opposite sides...

Answer 10

so what about the figure?

Answer 11

@3mar has the most simplest solution. A more complicated solution is to reflect over the y axis to get the green figure you see in the link

Then you'll rotate the green figure 180 degrees around the origin (0,0) to make it line up with the blue figure

move the slider around to see the rotation in action

this was done a while back with a similar problem. Instead of a rectangle, it's a parallelogram, but it's the same basic idea

Answer 12

across the y axis 90 degrees! but it's rotating clockwise...

Answer 13

I think its B cause look what happens when you rotate it the OTHER way.
