A(-3,-3) A is a glide reflection where the translation is (x,y) (x+5,y), and the line of reflection is y=1. what are the coordinates of A

Respuesta :

Answer:

Glide Reflection: It is a composition of transformations.

In glide reflection, a translation is first performed on the figure then it is reflected over a line.

Given:

The coordinate of A = (-3,-3)

The rule of translation is [tex](x,y) \rightarrow (x+5 , y)[/tex] and the line of reflection is y=1.

Now,

First applying the rule of translation we get;

[tex] A(-3, -3) \rightarrow (-3+5, -3)[/tex] = (2 , -3)

Since, -3 which is 4 unit below the line of reflection,

then,

after the reflection, over the line  y=1 we get, the reflected point A' would be 4 units above the line of reflection

so, A' (2, 1+4) =(2,5)

Therefore, the coordinate of A' (2,5).

The coordinates of A is [tex]\boxed{\left( {2,5} \right)}.[/tex]

Further explanation:

Translation can be defined as to move the function to a certain displacement. If the points of a line or any objects are moved in the same direction it is a translation.

Explanation:

The translation mapping of a single translation can be expressed as follows,

[tex]\left( {x,y} \right) \Rightarrow \left( {x + h,y + k} \right)[/tex]

Here, h represents the distance of translation in x-axis and k represents the distance of translation in y-axis.

The coordinates of A after reflection is [tex]\boxed{\left( {2,5} \right)}.[/tex]

The translation rule is [tex]\left( {x,y} \right) \to \left( {x + 5,y} \right)[/tex]

The coordinates after translation can be obtained as follows,

A [tex]\left( { - 3,3} \right) \to \left( { - 3 + 5, - 3} \right) = \left( {2, - 3} \right)[/tex]

The reflection is along [tex]y = 1[/tex]. Therefore, only y-coordinate will change and the x-coordinate remain the same.

-3 is 4 units below the reflection line [tex]y = 1.[/tex]

Therefore, the coordinate of A after reflection can be obtained as follows,

A [tex]\left( {2,1 + 4} \right) = \left( {2,5} \right)[/tex]

Hence,the coordinates of A is [tex]\boxed{\left( {2,5} \right)}[/tex].
