This diagram shows a pre-image △ABC , and its image, ​ △A′′B′′C′′ ​, after a series of transformations.

Select from the drop-down menus to correctly complete the statements.

△ABC is _____________ to become △A′B′C′ . Then ​ △A′B′C′ ​ is ___________ to become ​ △A′′B′′C′′ ​ . Because the transformations are __________, the pre-image and image are _______________.

1. A) reflected across the y-axis
B) reflected across the line y = x
C) rotated 180 degrees about the origin

2. A) reflected across the x-axis
B) translated 3 units down
C) rotated 90 degrees counterclockwise about the origin

3. A) both rigid
B) not both rigid

4. A) congruent
B) not congruent

Answer 1

ABC is rotated to become A'B'C, so I believe it would be C. "rotated 90 degrees counterclosewise about the orgin"

Answer 2

1. or 2. ?

Answer 3

Also, we have A'B'C which is translated to become A"B"C therefore, it'll be B. " translated 3 units down "

Answer 4

Sorry I didn't make it understandable for you, that would be 1

Answer 5

please go in order for me

Answer 6

1. ABC is rotated to become A'B'C, so I believe it would be C. "rotated 90 degrees counterclosewise about the orgin"

2. Also, we have A'B'C which is translated to become A"B"C therefore, it'll be B. " translated 3 units down "

3. I think it would be A. both rigid.

4. The pre-image and image are congruent so you'd choose A. congruent

Answer 7

Now, I'm not completely sure with my answer, but I hope that helped! You'd probably have to get validation from someone that way more mathematically inclined then I am.

Answer 8

k

Answer 9

I'll message you the people who'd I recommend you to get help with.

Answer 10

1. says 180

2. says 90
