# What is a translation reflection and rotation?

## What is a translation reflection and rotation?

Translation is when we slide a figure in any direction. Reflection is when we flip a figure over a line. Rotation is when we rotate a figure a certain degree around a point. Dilation is when we enlarge or reduce a figure.

## What is the rule for glide reflection?

A glide reflection is a composition of transformations.In a glide reflection, a translation is first performed on the figure, then it is reflected over a line. Therefore, the only required information is the translation rule and a line to reflect over.

**Is a glide reflection the same as a rotation?**

A glide reflection can be seen as a limiting rotoreflection, where the rotation becomes a translation.

**Is a glide reflection translation?**

Glide reflection is the composition of translation and a reflection, where the translation is parallel to the line of reflection or reflection in line parallel to the direction of translation. A glide reflection is – commutative and have opposite isometry.

### Why are translations reflections and rotations called rigid transformations?

A translation (notation T a,b ) is a transformation which “slides” a figure a fixed distance in a given direction. In a translation, ALL of the points move the same distance in the same direction. A translation is called a rigid transformation or isometry because the image is the same size and shape as the pre-image.

### Can a glide reflection have two translations?

The only way to get from the pre-image to the image is with a combination of one reflection and one translation. And because you can produce the translation part with two reflections, you can achieve a glide reflection with three reflections.

**Is translation rigid or Nonrigid?**

Whether that be translation, rotation, or reflection, you are not changing the shape’s original form in any way, you are just changing its position in space. Non-Rigid Transformations actually change the structure of our original object. For example, it can make our object bigger or smaller using scaling.

**What are the two transformations of a glide reflection?**

In a way glide reflection is somewhat different from the other three, because it s not a simple tranformation. Iin fact it is a combination of two transformations: translation and reflection. A combination of two but used as a single combined transformation.

#### Can a glide reflection have two reflections?

How many reflections are in a glide reflection? And because you can produce the translation part with two reflections, you can achieve a glide reflection with three reflections. Some images are just one reflection away from their pre-images; other images (in translation and rotation problems) are two reflections away.

#### How is a reflection like a translation?

Reflection is flipping an object across a line without changing its size or shape. Rotation is rotating an object about a fixed point without changing its size or shape. Translation is sliding a figure in any direction without changing its size, shape or orientation.

**What is the difference between reflection rotation and translation?**

Reflection is flipping an object across a line without changing its size or shape. Rotation is rotating an object about a fixed point without changing its size or shape. Translation is sliding a figure in any direction without changing its size, shape or orientation.

**What is the difference between a glide reflection and a translation?**

The combination of a reflection in a line and a translation in a perpendicular direction is a reflection in a parallel line. However, a glide reflection cannot be reduced like that. Thus the effect of a reflection combined with any translation is a glide reflection, with as special case just a reflection.

## What is a glide reflection of the plane?

Definition: A glide reflectionof the plane is an isometry of the plane that is a composition TR, where R is reflection in a line m and T is translation by a vector v parallel to m. Propostion: If G is a glide reflection defined as TR above, then G^2 = the translation T^2.

## What is glide reflection isometry?

Glide reflection is another type of isometry. The definition of Glide Reflection is a transformation consisting of a translation followed by a reflection in a line parallel to the slide arrow.
