**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:

Pre-image | Image |

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