## What is Reflection and Shear?

### Reflection:

Reflection is that the mirror image of original image in various word we are able to say that it is a rotation operation with 180° inflection transformation.

Size of a object does not change.

### Shear:

A transformation that slands the shape of an object is called shear transformation there are two type of shear transformation.
1) X Shear
2) Y Shear
The X shear preserve the Y co-ordinate and change are made to X co-ordinate which cause the vertical lines to till right or left according to figure.

The transformation Matrix for X shear may be represented as
[X’ Y'] = [XY] + Shy. [XY]
Where Shy is the shearing factors with respect to y module.
Similarly, the y shear preserves and change the Y co-ordinate which causes the horizontal line to transformer information LINE which shapes up or down as shown in the figure.

The y Shear can be represented as [X’ Y’] = [X Y] + Shx.[XY]
Where shx is the Shear factor with respect to X co-ordinate.
