## Is the transformation an isometric transformation?

An isometric transformation (or isometry) is a shape-preserving transformation (movement) in the plane or in space. The isometric transformations are reflection, rotation and translation and combinations of them such as the glide, which is the combination of a translation and a reflection.

## Which of the following transformations is not an isometric transformation?

Dilation changes the size of the shape making it a NON-ISOMETRIC transformation.

## Which of the following is not an isometric transformation of the pre image?

Therefore, translations, reflections, and rotations are isometric, but dilations are not because the image and preimage are similar figures, not congruent figures.

## Is a dilation an isometric transformation?

( Isometric means that the transformation doesn’t change the size or shape of the figure.) A fourth type of transformation, a dilation , is not isometric: it preserves the shape of the figure but not its size.

## What is the difference between an isometric transformation and a non-isometric transformation?

not preserve the distances and angles between a pre-image and its image. So, in a non- isometric transformation the image is a different size or shape than its pre-image. There are a lot more examples of non-isometric transformations but the above are the more recognizable examples.

## Are isometric transformations and rigid motions the same?

An ISOMETRIC TRANSFORMATION (RIGID MOTION) is a transformation that preserves the distances and/or angles between the pre-image and image. A NON-ISOMETRIC TRANSFORMATION (NON-RIGID MOTION) is a transformation that does not preserve the distances and angles between the pre-image and image.

## Are all squares isometric transformations?

Jeff claims that all squares would be isometric transformations because every square has four equal sides and four equal angles. An isometry is a transformation in the plane where the pre-image and image are identical. Isometries preserve the distances, angles, collinearity, and parallelism of the two shapes.

## What is an example of a non-isometric transformation?

2. Give an example of a non-isometric transformation and an isometric transformation. … preserve Translation, rotation & reflection are examples of isometric transformations stretch + dilation are examples of non-150 metrie transformations.

## Why is a dilation not an isometric transformation?

An isometry, such as a rotation, translation, or reflection, does not change the size or shape of the figure. A dilation is not an isometry since it either shrinks or enlarges a figure. … An isometry is a transformation where the original shape and new image are congruent.

## Which of the following properties is not preserved in an isometric transformation?

A transformation that preserves side lengths and angle measures. Direction isn’t preserved << translations, reflections, & rotation >> Also called an isometry. A transformation that results from two or more transformations.

## Which is an example of an isometric transformation?

A typical example of isometric transformation (transformation of congruence) is the physical motion of a solid, where the distance between any two of its points remains unchanged (congruent) and consequently, the whole solid itself remains unchanged.
