Question

Triangle PQR is transformed to similar triangle P′Q′R′ below:

A coordinate plane is shown.

What is the scale factor of dilation?

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

Answer 1

find the respective lengths and then you can just compare the corresponding sides

Answer 4

what scale factor would make a side length go from 3 to 1?

Answer 5

1/3 @jenny1994

Answer 6

that's the answer. notice how PQ = 3 P'Q'=1
3x=1
x=\(\dfrac{1}{3}\)

Answer 7
