## How do you read out loud coordinates?

The line of latitude is read as 41 degrees (41°), 24 minutes (24′), 12.2 seconds (12.2”) north.

The line of longitude is read as 2 degrees (2°), 10 minutes (10′), 26.5 seconds (12.2”) east.

The line of latitude is read as 41 degrees (41), 24.2028 minutes (24.2028) north..

## What are the three ways to write a translation?

There are three ways we describe a translation: Words. Coordinate Notation.

## What is the rule for coordinates?

How to read and plot coordinates. Coordinates are always written in brackets, with the two numbers separated by a comma. Coordinates are ordered pairs of numbers; the first number number indicates the point on the x axis and the second the point on the y axis.

## What information is needed to describe a reflection?

When describing a reflection, you need to state the line which the shape has been reflected in. The distance of each point of a shape from the line of reflection will be the same as the distance of the reflected point from the line. When describing a rotation, the centre and angle of rotation are given.

## What are the 4 types of transformations?

There are four main types of transformations: translation, rotation, reflection and dilation. These transformations fall into two categories: rigid transformations that do not change the shape or size of the preimage and non-rigid transformations that change the size but not the shape of the preimage.

## What are the coordinate rules for translations?

Rules: A positive integer describes a translation right or up on a coordinate plane. A negative integer describes a translation left or down on a coordinate plane. *A movement left or right is on the x-axis. A movement up or down is on the y-axis.

## How do you write a translation equation?

Key PointsA translation is a function that moves every point a constant distance in a specified direction.A vertical translation is generally given by the equation y=f(x)+b y = f ( x ) + b . … A horizontal translation is generally given by the equation y=f(x−a) y = f ( x − a ) .

## How do you plot coordinates?

Plot the coordinate (2,3)The first number in the brackets relates to the x axis.The 2 means move two places to the right, along the x axis.The second number in the brackets relates to the y axis.The 3 means move three places up, along the y axis.

## What is a rule for reflection?

The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same. For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P’, the coordinates of P’ are (5,-4).

## Which transformation of X Y is a dilation?

A dilation is a type of transformation that enlarges or reduces a figure (called the preimage) to create a new figure (called the image)….Rules for Dilations.Scale Factor, \begin{align*}k\end{align*}Size change for preimage\begin{align*}0 < k < 1\end{align*}Dilation image is smaller than preimage2 more rows•Apr 30, 2013

## What is the translation rule for a graph?

The Rule for Horizontal Translations: if y = f(x), then y = f(x-h) gives a vertical translation. The translation h moves the graph to the left when h is a postive value and to the right when h is negative value. Remember that these translations do not necessarily happen in isolation.

## What are the two rules of reflection?

The laws of reflection are as follows:The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane.The angle which the incident ray makes with the normal is equal to the angle which the reflected ray makes to the same normal.More items…

## How do you write a rule for reflection?

To write a rule for this reflection you would write: rx−axis(x,y) → (x,−y). Notation Rule A notation rule has the following form ry−axisA → B = ry−axis(x,y) → (−x,y) and tells you that the image A has been reflected across the y-axis and the x-coordinates have been multiplied by -1.

## What is the general rule for a vertical transformation?

Formally: For any function f(x), the function g(x) = f(x) + c has a graph that is the same as f(x), shifted c units vertically. If c is positive, the graph is shifted up. If c is negative, the graph is shifted down.

## Why do we use coordinates?

Coordinates systems are often used to specify the position of a point, but they may also be used to specify the position of more complex figures such as lines, planes, circles or spheres. For example, Plücker coordinates are used to determine the position of a line in space.

## What is the rule for transformation?

The function translation / transformation rules: f (x) + b shifts the function b units upward. f (x) – b shifts the function b units downward. f (x + b) shifts the function b units to the left.

## How are translations written?

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. There are two types of notation to know. … The second notation is a mapping rule of the form \begin{align*}(x, y) \rightarrow (x-7, y+5)\end{align*}.
