Question

What is the type of dilation and what is the scale factor?

Answer 1

We have that in the first one the dilation is a reduction and the scale factor is 1/2 with the scale factor we prove that the dilation is a reduction.

In the second one we have that the dilation is an enlargement and the sclae factor is 3 with the scale factor we prove that the dilation is an enlargement.

We can find the sacle factor with the next equation

`scale\text{ factor = }(image)/(preimage)`

you can take a side or the area of the figures and find the scale factor, for example in the first one we can do with one side od the triangle

`(image)/(preimage)=(4)/(8)=(1)/(2)\text{.}`
