Transformation involves moving a segment away from its original location.
The length of A'B' is 2cm
The length of AB is given as:
[tex]AB = 2cm[/tex]
From the complete question, we understand that AB was translated to A'B'
Translation is a rigid transformation.
This means that it does not alter the length of the segment that is being translated.
So, the length of A'B' is represented as:
[tex]A'B' = AB[/tex]
Substitute 2cm for AB
[tex]A'B' =2cm[/tex]
Hence, the length of A'B' is 2cm
