A rigid transformation is when a shape is moved with no changes to its shape whereas a size transformation is when a shape is moved with its shape becoming smaller or larger.
rigid transformation is for same modality(CT-CT) nad it can only perform translation, rotation and scaling translation. whereas non rigid for multimodality and it can do streching and shriking too. it use demon algorithm .
In 2 dimensional space it is a translation vector which is a 2x1 column vector.
The object and its image are congruent.
You have to add on the number that you want to transform the graph by. For example to move the graph 2 units along the x-axis the transformation would be f(x+2).
dilation (APEX)
Stretch
A rigid motion transformation is one that preserves distances and angles between points in a geometric shape. Anything that involves changing the size or shape of the object, such as scaling or shearing, would not describe a rigid motion transformation.
Rigid motion
Spinning a spinner.
A rigid transformation means it has the same size and shape so it would be a dilation

Flexing is one such transformation.
A rigid transformation is a geometrical term for the pre-image and the image both having the exact same size and shape.
In 2 dimensional space it is a translation vector which is a 2x1 column vector.
A transformation is said to be rigid if it preserves relative distances.
