I'm offering 20 points- figure a'b'c'd' is a dilation of figure abcd find the scale factor classify the dilation as an enlargement or a reduction. scale factor 1/3 ; as a reduction scale factor 1/4 ; as a reduction scale factor 3 ; enlargement scale factor 4 ; enlargement

Third option is correct. Scale factor 3 ; enlargement.

Step-by-step explanation:

It is given that the figure A'B'C'D' is a dilation of figure ABCD.

We know that after dilation the corresponding sides of image and preimage are in the same proportion.

The image of AD is A'D'.

From the figure it is noticed that the A(-1,2), D(-1,-1), A'(-3,6) and D'(-3,-3).

Distance formula is

Scale factor is constant which represents the relation between image and preimage.

Therefore the scale factor is 3.

If k>0 it means enlargement and if k<0 it means reduction. Therefore third option is correct.

a. is correct
