What is a geometric transformation?

A definite change in a geometric shape is called a geometric transformation. The transformation could be in the form of its position, size or shape.

In the figure given above, the original figure is the pre-image, and the newly formed figure is the image.

The pre-image is denoted by

$A$ ,

$B$ ,

$C$ , and so on. The image is represented by

$A'$ ,

$B'$ ,

$C'$ and so on.

Example:

In the above examples, the pre-images transformed into the images with different names.
