In geometry, transformation refers to the movement of objects in the coordinate plane.
Geometric transformations involve taking a preimage and transforming it in some way to produce an image. There are two different categories of transformations:
The rigid transformation, which does not change the shape or size of the preimage.
The non-rigid transformation, which will change the size but not the shape of the preimage.
This can be done for example by for example :
1. Rotation involves flipping the object over a line called the line of reflection.
