Question

I need help with coordinates please.
Triangle DOG is transformed using a reflection.

Triangle DOG is shown. D is at 0, 0, O is at 1, 2, G is at negative 1, 4.

Which could be coordinates of D'O'G' after the reflection?

D=(0,0), O=(-1,-2), G=(1,4)

D=(0,0), O=(-1,-2), G=(1,-4)

D=(0,0), O=(-2, 1), G=(-1, -4)

D=(0,0), O=(-1,2), G=(1,4)

Answer 1

Okay well if the reflection is over the x-axis you have to do (x, y) ---> (x,-y) and over the y-axis you would have to do (-x,y)

Answer 2

now see which of those coordinates when followed all the way through of either x or y would give the correct the coordinates :)

Answer 3

Thank you!

Answer 4

@yeamraz I know this was 8 months ago but can you help me with the same problem i don't understand the (x,y) stuff

Answer 5

Well you gotta plot these points and see where it could be reflected:)

Answer 6

So it would be D?

Answer 7

@yeamraz

Answer 8

exactly Lyn:)

Answer 9

ur good at this

Answer 10

Thanks :)
