What step are you on?
1. I don't know where to begin.
2. I have begun but got stuck midway.
3. I got an answer but I was told that it's wrong.
4. I got an answer and would like my work checked.
5. I have a question about someone else's work/solution.
6. I have completed the problem and don't need help anymore. Thank you.
7. None of the above

Do you still need help?

#

Yes pls

#

Okay, cool!

#

So firstly, I want you to tell me the difference between ABCD and A'B'C'D'.

versed sun Dec 5, 2025, 2:07 AM

#

ABCD is the pre image before a transformation and A’B’C’D’ is the after

glad sigil Dec 5, 2025, 2:08 AM

#

Yup! Now what's the difference in their shapes? You don't have to use mathematical terms, just tell me what you notice.

versed sun Dec 5, 2025, 2:08 AM

#

One is smaller than the other

glad sigil Dec 5, 2025, 2:09 AM

#

Yup! Now what about their position? Have they been rotated, translated, or reflected?

versed sun Dec 5, 2025, 2:10 AM

#

Translated?

glad sigil Dec 5, 2025, 2:10 AM

#

Yup! Well done, you're doing so well!!!

#

So now that we know the sizes are different, and it was translated, what are the two transformations needed? We'll get to order later.

#

Dilation and translation

glad sigil Dec 5, 2025, 2:11 AM

#

Yes, well done!!

#

Now, can you guess which one you would do first?

versed sun Dec 5, 2025, 2:12 AM

#

Dilation?

glad sigil Dec 5, 2025, 2:13 AM

#

Yup! Well done! Can you put in the answer now?

versed sun Dec 5, 2025, 2:14 AM

#

I don’t know how to find the scale factor for the dilation

glad sigil Dec 5, 2025, 2:14 AM

#

Oh I see.

#

In order to measure the dilation, you have to measure one side of both equations and divide them by [SIDE]'/[SIDE], get it?

#

So if A' was 10, for example, and A was 5...

#

10/5 is 2, so the scale factor is 2

#

It's essentially how much you have to multiply ABCD by to get to the same size as A'B'C'D'

versed sun Dec 5, 2025, 2:18 AM

#

Ohh

glad sigil Dec 5, 2025, 2:18 AM

#

Can you try it by yourself for me?

versed sun Dec 5, 2025, 2:19 AM

#

So for A the coordinates are (3,3) and A’(-3,1) so is the scale factor -1/3?

glad sigil Dec 5, 2025, 2:20 AM

#

Sooo close! The x-values dont matter when it comes to dialations, only the y. Count out how many units the sides are, then divide by A' Side Length/A Side Length.

versed sun Dec 5, 2025, 2:21 AM

#

So 1/3?

glad sigil Dec 5, 2025, 2:21 AM

#

Yup!! Well done!!

#

Remember, dialations can never be negative.

versed sun Dec 5, 2025, 2:24 AM

#

Okay thank you!

#

After that it’s a translation right

glad sigil Dec 5, 2025, 2:24 AM

#

yup!

#

All you have to go is find out how many units you have to move ABCD to get

#

into the position of A'B'C'D'

#

I recommend only looking at one point

#

So if A was at (0,0), and A' was at (1,1), the answer would be 2, brcause you move A 2 units to get to (1,1)

versed sun Dec 5, 2025, 2:29 AM

#

Ohhh

#

I got it!

#

Thank you!
