Figure A’B’C’D’ is a dilation of figure ABCD. Find the scale factor. Classify the dilation as an enlargement or a reduction.

(1 point)

Scale factor one-third; reduction
Scale factor one-fourth; reduction
Scale factor 3; enlargement*
Scale factor 4; enlargement

We can not see the picture, thus are unable to help. If the new picture is BIGGER then it is an enlargement.

You chose scale factor 3, so check an original point and see if it is increased by a factor of 3 : )
Hope this helps, again... we can't see the transformation.

To find the scale factor, we need to compare the corresponding side lengths of the two figures.

Let's compare the lengths of side AB and A'B'. If the scale factor is one-third, then AB should be three times longer than A'B'. However, if the scale factor is one-fourth, AB should be four times longer than A'B'.

Similarly, if the scale factor is 3, AB should be one-third of A'B', and if the scale factor is 4, AB should be one-fourth of A'B'.

Since the given figure A'B'C'D' is a dilation of ABCD, the length of AB should be proportional to the length of A'B'. Therefore, if AB is longer than A'B', it is an enlargement, and if AB is shorter than A'B', it is a reduction.

From the given answer choices, the correct option is:
Scale factor 3; enlargement

To find the scale factor of a dilation, you need to compare the corresponding side lengths of the original figure and its dilation.

In this case, we are given two figures: ABCD and A’B’C’D’, where the latter is a dilation of the former.

To find the scale factor, we can compare the lengths of corresponding sides.

Let's consider a specific side, for example, side AB in figure ABCD. Now, let's compare it with its corresponding side A'B' in figure A'B'C'D'.

If the length of AB is 3 units and the length of A'B' is 1 unit, we can see that the dilation has reduced the length of AB by a factor of 3.

Therefore, the scale factor is 1/3.

Since the scale factor is less than 1 (specifically, one-third), this dilation is classified as a reduction.

So, the correct answer is: Scale factor one-third; reduction.
