In this video, I am explaining the Transformations.

A transformation is a process that manipulates a polygon or other two-dimensional object on a plane or coordinate system. Mathematical transformations describe how two-dimensional figures move around a plane or coordinate system.

A preimage or inverse image is the two-dimensional shape before any transformation. The image is the figure after transformation.

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.

Types of Transformations

Within the rigid and non-rigid categories, there are four main types of transformations that we'll learn today. Three of them fall in the rigid transformation category, and one is a non-rigid transformation.

Rotation: rotating an object about a fixed point without changing its size or shape
Translation: moving an object in space without changing its size, shape or orientation
Dilation: expanding or contracting an object without changing its shape or orientation
Reflection: flipping an object across a line without changing its size or shape
