A rigid motion is a transformation in geometry that preserves the shape and size of a figure. This means that distances between points and angles remain unchanged during the transformation. Common types of rigid motions include translations, rotations, and reflections. Since the original figure and its transformed image are congruent, rigid motions do not alter the overall structure of the figure.
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.
A rigid motion transformation is a type of transformation that preserves distances and angles. An example of this is a rotation, where a shape is turned around a fixed point (the center of rotation) without altering its size or shape. For instance, rotating a triangle 90 degrees around its centroid keeps the triangle's dimensions the same while changing its position. Other examples include translations (sliding) and reflections (flipping).
Rigid motion refers to a transformation of a geometric figure that preserves distances and angles, meaning the shape and size of the figure remain unchanged. Common types of rigid motions include translations (sliding), rotations (turning), and reflections (flipping). In essence, during a rigid motion, the pre-image and its image are congruent. This concept is fundamental in geometry, as it helps in understanding symmetries and maintaining the integrity of shapes during transformations.
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 .

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
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.
A transformation is said to be rigid if it preserves relative distances.
