## What does a rigid transformation preserve?

Rigid motion – A transformation that preserves **distance and angle measure** (the shapes are congruent, angles are congruent).

## What transformation does preserve orientation?

**Rotation and translation** preserve orientation, as objects’ pieces stay in the same order. Reflection does not preserve orientation.

## Do transformations change orientation?

Rotation, translation (shift) or dilation (scaling) won’t change the fact that the direction A→B→C is clockwise. … The way A’→B→C is counterclockwise. That is a manifestation of (1) our triangle has orientation and (2) the transformation of reflection **does not** preserve the orientation.

## Does rotation preserve orientation?

**Rotation preserves the orientation**. For example, if a polygon is traversed clockwise, its rotated image is likewise traversed clockwise. Rotation is isometry: a rotation preserves distances.

## What two things do all rigid transformations preserve?

Rigid transformations preserve **distance and angles**. All corresponding sides will be the same length and all corresponding angles will be the same measure.

## Does a rigid motion preserve side lengths?

Simply put, rigid motions are transformations that **preserve the side lengths and angles in a shape**. … The slide could be in any direction on the plane as long as it keeps its shape, and stays facing the same way. Rotation. A rotation is exactly what it sounds like.

## Which of the following transformations preserve the orientation of a figure?

**Reflection**: Reflection is a type of transformation in which the given image is flipped across a line of reflection to create the transformed image. In this transformation, dimensions of the figure is always preserved.

## Does a translation change orientation?

A translation is when a geometric figure slides up, down, left or right on the coordinate plane. The figure moves its location, but **doesn’t change its orientation**. It also doesn’t change its size or shape. When you perform translations, you slide a figure left or right, up or down.

## Why do reflections not preserve orientation?

Reflection preserve the distance between two points. … Reflection is a congruence transformation. Under a reflection the image is laterally inverted. Thus **reflection does NOT** preserve orientation.
