Your question: Is a stretch a rigid transformation?

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 are the 4 rigid transformations?

There are four types of rigid motions that we will consider: translation , rotation, reflection, and glide reflection.

How do you know if a transformation is rigid?

A basic rigid transformation is a movement of the shape that does not affect the size of the shape. The shape doesn’t shrink or get larger. There are three basic rigid transformations: reflections, rotations, and translations.

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 of the following is not a rigid motion transformation?

So the above mentioned forms – reflection, rotation and translation are part of rigid motion. Dilation is non rigid motion.

Is Dilation a rigid motion?

A dilation is not considered a rigid motion because it does not preserve the distance between points.
