Answer:
This is a reduction and the scale factor is 1/2
Explanation:
we know that
The dilation is a non rigid transformation that produces similar figures
If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor
Let
z ----> the scale factor
If the absolute value of the scale factor is greater than 1 then the dilation is a enlargement
If the absolute value of the scale factor is less than 1 then the dilation is a reduction
step 1
Find the scale factor
The scale factor is equal to the ratio of its corresponding sides
so
![z=(A'B')/(AB)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/mu3wme4o11gau344i1ftwf9xf45w0ybtar.png)
substitute the values
![z=(2)/(4)=(1)/(2)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/5qo15cw1eh0yuo6554x4z1a74qrkkhlbap.png)
The absolute value of the scale factor is less than 1
therefore
This is a reduction and the scale factor is 1/2
