## Which of these transformations is not a congruence transformation or isometry?

The only choice that involves changing the size of a figure is letter a) dilation and as a result, creates two figures that are NOT congruent.

## Which transformation is not and isometry?

A geometry transformation is either rigid or non-rigid; another word for a rigid transformation is “isometry”. 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.

## What transformation does not maintain congruence?

Students must understand that rotations, reflections, and translations preserve congruence but dilations do not unless the scale factor is one.

## Which transformations are Nonrigid transformations?

Translation and Reflection transformations are nonrigid transformations.

## Which of the following transformations does not preserve congruence?

A dilation is the only transformation that does not preserve congruency but preserves orientation.

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

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

## Which of the following is not a rigid transformation?

Types of transformations Translation, reflection, and rotation are all rigid transformations, while dilation is a non-rigid transformation. In non-rigid transformations, the preimage and image are not congruent.

## Which of the following is a congruence?

Two triangles are congruent if the side(S) and angles (A) of one triangle is equal to another. And the criterion for congruence of the triangle are SAS, ASA, SSS, and RHS.

## Are translations always congruent?

Recall from Lesson 14-1 that congruent figures are figures with the same size and shape and that a translation image is always congruent to its preimage. … A congruence transformation is a transformation under which the image and preimage are congruent. A congruence transformation is also called an isometry.

## Which transformation will produce similar but not congruent figures?

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.
