Question

if abc is dilated by a scale factor of 3, which statement is true of the image a'b'c'

Answer 1

answers please?

Answer 2

1) 3A'B'= AB
2)B'C'= 3BC
3) m<A'= 3(m<A)
4)3(m<C')=m<C

Answer 3

what do you think? Why?

Answer 4

I either a or b, I want to make sure

Answer 5

why do you think that? What is your reasoning?

Answer 6

@dumdumneedsgumgum

Answer 7

Yuo wouldn't want to multiply the scale factor with the dilated image

Answer 9

It my hw, I don't want to get it wrong, which this is the only question I want to ask

Answer 10

it's not a because A'B' are already dilated
You don't need to dilate it again

Answer 11

please read the link, come back, and tell me what you think

Answer 12

Sadly I failed this test..

Answer 13

Ok, thanks guys, And yeah, I had hard time doing these geometry, it not my best subject

Answer 14

Are you a FLVS student?

Answer 15

Nope

Answer 16

so, I just realized that in c and d, they are referring to the angles. My bad, I thought they were referring to the vertices. As such, your previous statement of A or B is correct. It is one of those two. So, the question now is which side length is bigger, since we a and be refer to the side length. Will the pre-image or the scaled image be larger?

Answer 17

sorry for the confusion.

Answer 18

Oh ok, I was a bit confused before as you said that a or b is not the correct one but thanks fibo

Answer 19

I misunderstood the notation. It has been a while since I have seen it. So anyways, which is bigger, then you will be able to figure out your answer

Answer 20

So the answer is B

Answer 21

let the OP figure it out please

Answer 22

Sorry :P

Answer 23

It ok, I knew it could be b

Answer 24

Thanks guys, you help me a lot

Answer 25

It's ok, for future reference though, we want to let the OP come to their conclusion. Then if they don't understand, we can explain more.

Sorry again about the original misconception. I read it as the vertices/coordinates of points not angles and sides

Answer 26

Don't need to say sorry fibo, as you said you have not see this question for a while. But thanks guys (fibo and gabe) you guys help me a lot
