Question

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

reflection in where

Answer 2

Triangle DOG is transformed using a reflection.

Answer 3

thats all it says .-.

Answer 4

im guessing accross the x axis..
so the reflection over the x axis is.
(x,y) ==> (x,-y)

Answer 5

g (-1,4)
d(0,0)
o(1,2)
those are your current coordinates.

Answer 6

OHHH i got it. could you look at a few more ?

Answer 7

i dont want to.

Answer 8

but ok

Answer 9

ask away

Answer 10

lol you dont have to but
What additional information would you need to prove that ΔABC ≅ ΔDEF by ASA?
segment AB ≅ segment DE

segment BC ≅ segment EF

segment AB ≅ segment FE

segment BC ≅ segment ED

Answer 11

ASA = angle side angle
you have two angles congruent..
so you need a side.
AB = DE
those two are both the same type of legs of the triangle
it could also be
AC = DF
or
BC = FE

Answer 12

OHH OKAY ! thank you (:
