In geometric transformation, a figure is mapped to another form another figure. The points in original image are called preimage of the points formed in the transformed figure that is called image.
In geometric transformation, a figure is mapped to another form another figure. The points in original image are called preimage of the points formed in the transformed figure that is called image.
There are four types of transformations:
translation
reflection
dilation
rotation
In the given case the figure is translated i.e. all the points in the preimage moved with the same distance and direction. As B is preimage of B'
