OpenStudy (welshfella):

If you translate the smaller circle then dilate it at center of larger circle then they are similar

OpenStudy (josedavid):

what do i write

OpenStudy (welshfella):

translation wil be ( x +/- a) , (y +/-b) then the dialtion factor

OpenStudy (welshfella):

what do you need to do to x and y coordinates to translate point D to point B

OpenStudy (welshfella):

Hint x coordiante of D must go 8 units the the left so thats (x - 8)

OpenStudy (welshfella):

now how many units of y must you go up to get to point B?

OpenStudy (welshfella):

check the picture

OpenStudy (welshfella):

just visualise a moe of the point D 8 units to the left horizzonatally then so many up till you get to point B

OpenStudy (welshfella):

How many units have you got to go up to get to B?

OpenStudy (welshfella):

It's not rocket science.

OpenStudy (welshfella):

hmmm talking to myself....
