Question

Triangle PQR is transformed to similar triangle P'Q'R'.

What is the scale factor of dilation?

1 over 2
1 over 3
1 over 4
1 over 5


Please explain your work, it'd really help if I understood why that's the answer then just accepting an answer. I'm really confused so please, if you can, explain your work!

Answer 1

1/2

Explanation:

Answer 2

The answer is 1/2

Explanation:

If you look at the distance between P and R and the dilation between P' and R' you would get 4 and 2. This the scale dilation is 1/2. Multiply 1/2 by 4 and you would get 2.
