geometry

OpenStudy (anonymous):

DOG has coordinates D (3, 2), O (2, -4) and G (-1, -1). A translation maps point D to D' (2, 4). Find the coordinates of O' and G' under this translation.

OpenStudy (anonymous):

@sleepyjess last one please

OpenStudy (anonymous):

what is the difference between the x coordinate in D' and the x coordinate in D?

OpenStudy (anonymous):

what is the difference between the y coordinate in D' and the y coordinate in D?

OpenStudy (anonymous):

D' is 2 and D is 3

OpenStudy (anonymous):

so you subtract 1 from x coodinate in D to get the x coordinate in D' correct?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

ok so now how would you get from the x coordinate in O to the x coordinate in O'?

OpenStudy (anonymous):

so 2 - 1?

OpenStudy (anonymous):

correct, so what is the x coordinate in O'?

OpenStudy (anonymous):

1

OpenStudy (anonymous):

perfect, now just repeat that for the x coordinate in G' and then find the difference of y coordinates in D and D' and repeat that for O' and G'

OpenStudy (anonymous):

so is will be O' (1,-2)?

OpenStudy (anonymous):

perfect

OpenStudy (anonymous):

and G' will be (-2,1)

OpenStudy (anonymous):

perfect, nice work

OpenStudy (anonymous):

ty so much for helping me :D

OpenStudy (anonymous):

yw :)

OpenStudy (anonymous):

uhm can you help check this one question? i have the answer but just wondering if is correct? @billj5

OpenStudy (anonymous):

If TOY congruent STU, then what corresponding side is congruent to side US?

OpenStudy (anonymous):

so is YT?

OpenStudy (anonymous):

no try drawing the triangles and labeling

OpenStudy (anonymous):

actually nvm you are correct, sorry lol

OpenStudy (anonymous):

Is alright ty though :D)

OpenStudy (anonymous):
