## What are the 3 types of rigid transformations we looked at in Lesson 2?

In the next few lessons, we learn about three kinds of simple rigid motions: translation, reflection, and rotation. We call these the basic rigid motions. each of these basic rigid motions has on the points in the plane. We begin with translations or, more precisely, a translation along a given vector.

## What type of transformations are rigid transformations?

The rigid transformations include rotations, translations, reflections, or their combination.

## Is reflection rigid or Nonrigid?

Whether that be translation, rotation, or reflection, you are not changing the shape’s original form in any way, you are just changing its position in space. Non-Rigid Transformations actually change the structure of our original object. For example, it can make our object bigger or smaller using scaling.

## What does rigid mean in maths?

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.

## Is dilation a rigid motion?

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

## Is dilation a rigid transformation?

Rigid motions are transformations that move an image, but do not change the size. The only transformation that is not a rigid motion is dilation. A dilation is a transformation that changes the size of a figure.
