Answer 1

Answer:

Option D is correct.

Explanation:

From the given figure,

Labelled the black triangle as A, B and C

The coordinates of  triangle ABC are;

A= (2,8) , B= (2,5) and C=(6,5)

To find the glide reflection image of the triangle ABC.

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 rule of translation is: $(x,y) \rightarrow (x, y-7)$ and line of reflection is x= 1.

Now, apply the rule of translation on black triangle, we get;

$A (2,8) \rightarrow (2, 8-7)$ = A' (2,1)

$B (2,5) \rightarrow (2, 5-7)$ =B' (2,-2)

$C (6,5) \rightarrow (6, 5-7)$ = C' (6,-2)  

Next,

Apply the rule of reflection over the line x =1,

i.e, $(x,y) \rightarrow (-x+2, y)$

$A' (2,1) \rightarrow (-2+2, 1)$ =A" (0,1)

$B' (2,-2) \rightarrow (-2+2, -2)$ =B" (0,-2) and

$C' (6,-2) \rightarrow (-6+2, -2)$ =C" (-4,-2)

You can see the graph of Glide reflection as shown below in the attachment.
