Choose exactly two answers that are correct.



A.
Triangle XYZ was dilated by a scale factor of to produce triangle XꞌYꞌZꞌ.

B.
Triangle XYZ was translated 3 units up to produce triangle XꞌYꞌZꞌ.

C.
Triangle XꞌYꞌZꞌ was translated 4 units down and 4 units left to produce triangle XꞌꞌYꞌꞌZꞌꞌ.

Answer 5

I think you're missing something there in A :P

Answer 6

yea supposed to be 1/3 sorry

Answer 7

Well it definitely wasn't translated, right?

Answer 8

yea

Answer 9

It had to be dilated. When you dilate something, it either gets bigger, or smaller. What happened to this one?

Answer 10

i think it got bigger or smaller i think smaller

Answer 11

Yup, the bigger triangle is the original. The dotted triangle is smaller one. So it basically shrank. When you dilated something, usually if the factor is greater than 1, it gets bigger. So since this one didn't grow, we can eliminate that it got dilated by a factor of 3. What does that leave? :P

Answer 12

I am thinking B & C

Answer 13

Nope, if it was translated, the triangle would of stayed the same size, it just would of moved. This one got smaller, it didn't move.

Answer 14

A & B?

Answer 15

It got smaller. Since 1/3 is smaller than 1, we could say it was dilated by a factor of 1/3.

Answer 16

A& C? I have to pick two

Answer 17

Two? Strange. But yess, those are the only dilated options.

Answer 18

Thank you

You're welcomeee
