## How do you explain translation in math?

A translation is a type of transformation that moves each point in a figure the same distance in the same direction. Translations are often referred to as slides. You can describe a translation using words like “moved up 3 and over 5 to the left” or with notation.

## What are the 3 types of transformations?

Types of transformations:

- Translation happens when we move the image without changing anything in it.
- Rotation is when we rotate the image by a certain degree.
- Reflection is when we flip the image along a line (the mirror line).
- Dilation is when the size of an image is increased or decreased without changing its shape.

## What is the mean of transformation?

: the act or process of changing completely : a complete change. transformation. noun.

## What is 3d transformation?

3-D Transformation : 3-D Transformation is the process of manipulating the view of a three-D object with respect to its original position by modifying its physical attributes through various methods of transformation like Translation, Scaling, Rotation, Shear, etc.

## Why are transformations required?

Transformation means changing somegraphics into something else by applying rules. When atransformation takes place on a 2D plane, it is called 2D transformation. Transformations play an important role in computer graphics to reposition the graphics on the screen and change their size or orientation.

## What is CG reflection?

Reflection in computer graphics is used to emulate reflective objects like mirrors and shiny surfaces. Approximate reflections can usually be computed faster by using methods such as environment mapping. Reflection on a shiny surface like wood or tile can add to the photorealistic effects of a 3D rendering.

## Is a transformation that produces mirror image of an object relative to axis of reflection?

A reflection is a transformation that produces a mirror image of an object relative to an axis of reflection. We can choose an axis of reflection in the xy plane or perpendicular to the xy plane. The table below gives examples of some common reflection.

## When two or more transformation is performed on the figure it is called as?

A composite transformation is when two or more transformations are performed on a figure (called the preimage) to produce a new figure (called the image).

## What is a double reflection?

The double reflections are equivalent to a rotation of the pre-image about point P of an angle of rotation which is twice the angle formed between the intersecting lines (theta). Remember that, by convention, the angles are read in a counterclockwise direction.

## Can any translation can be replaced by two reflections?

One way to replace a translation with two reflections is to first use a reflection to transform one vertex of the pre-image onto the corresponding vertex of the image, and then to use a second reflection to transform another vertex onto the image. Any translation can be replaced by two reflections.

## What is a composition of transformations?

A composition of transformations is to perform more than one rigid transformation on a figure. Glide Reflection: a composition of a reflection and a translation. The translation is in a direction parallel to the line of reflection.

## What is a composition of translations?

A composition of transformations is a combination of two or more transformations, each performed on the previous image. A composition of reflections over parallel lines has the same effect as a translation (twice the distance between the parallel lines).

## What is the composition of two reflections?

1. The composition of two reflections is a rotation.

## What is the rule for the reflection?

Reflection in the line y=−x : A reflection of a point over the line y=−x is shown. The rule for a reflection in the origin is (x,y)→(−y,−x) .

## How do you do a glide reflection?

A glide reflection is just what it sounds like: You glide a figure (that’s just another way of saying slide or translate) and then reflect it over a reflecting line. Or you can reflect the figure first and then slide it; the result is the same either way. The footprints are glide reflections of each other.

## What is a glide in math?

In 2-dimensional geometry, a glide reflection (or transflection) is a symmetry operation that consists of a reflection over a line and then translation along that line, combined into a single operation.
