Will give ! which types of dilation are the given scale factors? select expansion or contraction to correctly describe the type of dilation for each given scale factor. scale factor −54 38 −1.2 0.5

-

For 0.5 the dilation are reduction and for -54, -1.2 and 38 it is an enlargement.

Step-by-step explanation:

We know that, dilation is a transformation that changes the size of the figure. The two changes in the size are:

1. Enlargement i.e. makes the figure larger than the original

2. Reduction .i.e. makes the figure smaller than the original

Dilation depends on a scale factor say 'k'. Then:

1. If k > 1 , the figure is an enlargement

2. If k < 1 , the figure is a reduction.

The negative sign reflects the image and has no effect on dilation of a figure.

Now, we have scales -54, 38, -1.2, 0.5

So, using above concept, we get that,

For 0.5 the dilation are reduction

For -54, 38, -1.2 the dilation is an enlargement.
