Question

Question 8 options:

Pre-image ABCD is dilated to be image A'B'C'D'. What scale factor is used to create the dilation?

Answer 1

the scale factor is 2

Explanation:

we know that

If two figures are similar, then the scale factor is equal to the ratio of its corresponding sides

so

Let

z-----> the scale factor

`(A'B')/(AB)=(A'D')/(AD)`

substitute the values

`(4)/(2)=(6)/(3)`

`2=2` ----> is true

therefore

the rectangles are similar and the scale factor is 2
