# Does the transformation appears to be a rigid transformation?

Contents

## How do you know if a transformation is rigid?

A rigid transformation includes only rotation and translation. It does not include reflection, and it does not modify the size or shape of an input object.

## What is considered a rigid transformation?

Rigid just means that the whole shape goes through the same transformation, so with rotations, reflections, and translations, the shape should not change at all, just in a different place or orientation.

## What is not a rigid transformation?

A common type of non-rigid transformation is a dilation. A dilation is a similarity transformation that changes the size but not the shape of a figure. Dilations are not rigid transformations because, while they preserve angles, they do not preserve lengths.

## Which transformations are rigid transformation check all that apply?

Reflections, translations, rotations, and combinations of these three transformations are “rigid transformations”.

## Are all translations considered a rigid motion?

Rotations, reflections and translations are all considered rigid motion transformations. what defines a rigid motion transformation? The dilation of the shape stays the same no matter what.
