# Quick Answer: How do you know if two figures are similar by transformations?

Contents

## How do you determine if two figures are congruent using transformations?

Two figures are congruent if the second can be obtained from the first by a series of rotations, reflections, and/or translations.

## What are the similarities transformations?

▫ A similarity transformation is a composition of a finite number of dilations or rigid motions. Similarity transformations precisely determine whether two figures have the same shape (i.e., two figures are similar). … ▫ Both congruence and similarity transformations are a means of comparing figures in the plane.

## Do transformations create congruent shapes?

Congruence transformations are transformations performed on an object that create a congruent object. There are three main types of congruence transformations: Translation (a slide) Rotation (a turn)

## Is translation congruent or similar?

Rotations, reflections, and translations are isometric. That means that these transformations do not change the size of the figure. If the size and shape of the figure is not changed, then the figures are congruent.

## When a figure and its transformation image are similar?

A similarity transformation is one or more rigid transformations (reflection, rotation, translation) followed by a dilation. When a figure is transformed by a similarity transformation, an image is created that is similar to the original figure.

## What is an example of similarity?

The definition of a similarity is a quality or state of having something in common. When you and your cousin look exactly alike, this is an example of when the similarity between you two is striking. … The state or quality of being similar; resemblance or likeness.

## How are similarity transformations and congruence transformations alike and different?

Similar figures have the same shape but not necessarily the same size. Congruence transformations preserve length and angle measure. When the scale factor of the dilation(s) is not equal to 1 or −1, similarity transformations preserve angle measure only.

## Which series of transformations will create similar but not congruent figures?

The correct answer is: dilation and rotation.

## What transformations always produce congruent figures explain?

The transformations that always produce congruent figures are TRANSLATIONS, REFLECTIONS, and ROTATIONS. These transformations are isometric, thus, the figures produced are always congruent to the original figures.
