Question

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)
