## What transformation is similar but not congruent?

The correct answer is: **dilation and rotation**.

## Are dilated figures are similar but not congruent?

If **two figures are congruent**, then they are similar. If two figures are similar, then they are congruent. If an angle is dilated with the center of dilation at its vertex, the angle measure may change.

## Can you use transformations to prove that two figures are not congruent?

There is no sequence of rigid transformations that maps DEF to LMN. The lawns are not congruent. If the figures are not the same size, there is no rigid motion that can map one of them onto the other. The transformation would need to include a **dilation**, which is not a rigid motion.

## Are Δdef and Δrpq congruent?

Therefore, ΔDEF, **and ΔRPQ are congruent**, because ΔDEF can be mapped to ΔRPQ by a 180° rotation about the origin followed by a translation 2 units down.

## Do dilations always produce congruent figures?

Definition: The figure before a transformation has occurred. … A **dilation always produces a congruent figure**.

## Does a dilation produce a similar figure True or false?

The center of a dilation is always its own image. Dilations preserve angle measure, betweenness of points and collinearity. It does not preserve distance. Simply, **dilations always produce similar figures** .

## Which type of rigid transformation is shown Reflectionrotationtranslation?

A transformation that preserves length and angle measurement. Translations, reflections and rotations are three types of rigid transformation which is also called **congruence transformation** or isometry.

## What do congruent figures and similar figures have in common?

Congruent means being exactly the same. When two line segments have the same length, they are congruent. When **two figures have the same shape and size**, they are congruent. … Similar means that the figures have the same shape, but not the same size.

## Are transformations used to create similar figures?

A similarity transformation is a transformation in which the image has the same shape as the pre-image. … Similarity transformations also include **translations, reflections, and rotations**, with the addition of dilations. Similarity transformations preserve shape, but not necessarily size, making the figures “similar”.
