Question

To describe a sequence of transformation that maps triangle ABC onto triangle A"B"C", a student starts with a reflection iver the x-axis. How should the student complete the sequence of transformations to map triangle ABC onto triangle A"B"C"?

Answer 1

hint:
Find out where the point C would be after the reflection.
(reflection about x-axis: (x,y)->(x, -y) )
then translate point C to point C". The translation vector is C"-C.
You can as well use the point A or B.

Answer 2

Take point C to work on
C(4,4)
1st apply a reflection across x axis
(4,-4) then how would you get the previous coordinates to C'(6,2)?
Clearly by translation because the values have changed. Now sometimes it can be by enlargement or so on but in this case it's clear that the shapes have the same size.
So translation by the rule
(x + 2, y + 6)

Answer 3

Um could you explain that in English

Answer 4

Well @mathmate might do that. I only speak math language XD

Answer 5

@mathmate do you think you could explain this fully in English

Answer 6

@gabbyalicorn

Answer 7

idk

Answer 8

@Will.H Is a smart boii

Answer 9

@gabbyalicorn ok it was worth a shot I just want the English translation

Answer 10

I was just using the standard language you would be expected to have learned if you are presented with this problem.
The best idea for you is to review your material, give it a try, and tell us what you think.
In the worst case, you just have to draw the reflected image on graph (or paper) and decide what kind of translation is needed to bring the reflected image to A"B"C". You should be able to do at least that. If not, here's an article to help you with your revisions.
