## How do you rotate a reflection?

Video quote: *Negative 1 so what happened is we made the y-coordinate. Be the opposite sign we kept the x-coordinate the same you can see that's a-ok.*

## How do you translate reflections?

Video quote: *So all you got to do is multiply the y-coordinate by negative one that's how you can reflect it over the x-axis.*

## Can a translation rotate a shape?

Translation means a shape moves around a fixed point or across the mirror line without changing. Rotation means the shape turns as it moves around a fixed point. **Shapes can be rotated clockwise or anticlockwise by a certain number of degrees** (90 degrees would be a quarter turn, for example).

## How do you rotate a shape in transformations?

Step 1: Choose any point in the given figure and join the chosen point to the center of rotation. Step 2: Find the image of the chosen point and join it to the center of rotation. Step 3: Measure the angle between the two lines. The sign of the angle depends on the direction of rotation.

## How can you use reflections to translate a shape?

Video quote: *So I mean when we reflecting on a line we get a mirror image of a shape. So the distance between F and its reflection should have this line of symmetry as the midpoint.*

## Can we represent translation with reflection?

To graph a translation, perform the same change for each point. **You can identify a reflection by the changes in its coordinates**. In a reflection, the figure flips across a line to make a mirror image of itself. Take a look at the reflection below.

## How do you translate shapes?

In geometry translation means **moving a shape into a different position, without changing it in any way**. In Year 5 children are introduced to shape translation by giving them shapes on squared paper; they then need to be moved a certain number of squares up, down, left or right.

## How do you translate a figure?

In the coordinate plane we can draw the translation if we know the direction and how far the figure should be moved. To translate the point P(x,y) , a units right and b units up, **use P'(x+a,y+b)** .

## How do you find the translation of a shape?

Video quote: *Three four would mean three left four up the vector 3 negative 4 would mean three right four down and lastly the vector negative three negative four means three left. And fall down.*

## How do you do a translation?

Video quote: *Along the x axis. Next is the Y value of negative 1. We are going to subtract 1 from all of the Y coordinates. On the graph negative 1 means to move down vertically one unit along the y axis.*

## How do you translate a shape for kids?

Video quote: *The one called translation translation is essentially moving a shape from one place to another. In. This case I have a nice shape right here shape ABCD. And I Square.*

## How do you translate a shape on a graph?

Video quote: *Direction. By three units okay now the easiest way of doing that is to take one of the points. And simply look at the graph and read through the graph.*

## What does it mean to translate a shape?

A translation **moves a shape up, down or from side to side but it does not change its appearance in any other way**. Translation is an example of a transformation. A transformation is a way of changing the size or position of a shape. Every point in the shape is translated the same distance in the same direction.

## How do you translate shapes on Desmos?

Translation Maker. Add new points as desired in the table below to create larger polygons. **Drag red points to change the original shape**. Move the purple point to move the translated image.

## What is a reflected shape?

What does Reflecting a Shape Mean? Reflecting a shape simply means **to flip it over a mirror line**. Each point in the shape is moved to the other side of the mirror line but remains the same distance away from the line. The reflected image will now be facing in the opposite direction to the original object.

## What is a rotation shape?

What is Rotation of Shapes? **When a shape turns clockwise or anticlockwise around a fixed spot**. The size and the shape itself will remain the same, but its position in space will change.

## What is a rotated shape?

Rotating shapes means **moving them around a fixed point (clockwise or anticlockwise, and by a certain number of degrees)**. The shape itself stays exactly the same, but its position in the space will change.

## How do you reflect a shape in a mirror?

Video quote: *So let's draw this vertical line in down here so we just need to reflect the shape now in this mirror line let's start with the top corner. So the top corner is 1 square to the mirror.*

## How do you draw a reflected shape?

Video quote: *And locate the position that's also one square away from that side. And I know that the point that I highlighted on the original triangle is going to end up here once I've reflected it.*

## How do you translate a shape by a vector?

The top number of the vector tells you if you are moving the shape left or right. If the number is negative you move the shape left. If the number is positive you move the shape right. The bottom number of the vector tells you if you are moving the down or up.

## What does reflection across y =- 2 mean?

Video quote: *So when I make my line my line can only go across y equals negative two. So that's why I'm putting my mirror right there. So my mirror can only happen and it can only touch y equals negative two.*

## What does reflection over Y X mean?

When you reflect a point across the line y = x, **the x-coordinate and y-coordinate change places**. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x).

## How do you reflect a point over Y 3?

Video quote: *So you just take your x and y coordinates and swap them now again you're still going to graph this as that's the x coordinate that's the y coordinate.*

## What does it mean to reflect over Y =- 1?

the line y=1 is a horizontal line passing through all. points with a y-coordinate of 1. the point (3,10) reflected in this line. **the x-coordinate remains in the same position**.
