Answer:
A reduction with scale factor of 1/4
Explanation:
Since S'T'U'V' is smaller than STUV, the dilation is called reduction.
Then, the scale factor is calculated as
Scale factor = Length of image/ Length of original
So, using the segment ST, we get
Length of image = Length of S'T' = 1
Length of original = Length of ST = 4
Then
Scale factor = 1/4
Therefore, the answer is
a reduction with scale factor of 1/4
