May you help me with this problem? @ganeshie8 @beccaboo333

OpenStudy (broskishelleh):

A

OpenStudy (dumbcow):

no not A when 2 figures are similar but different sizes, the angles will be equal and the side length will be proportional to the dilation factor

OpenStudy (anonymous):

I read your explanation, but am a bit stuck . I think I should eliminate option c.

OpenStudy (dumbcow):

that is correct, the lengths are not equal

OpenStudy (dumbcow):

it was dilated by factor of 3 .... so ratio of lengths is 3:1

OpenStudy (anonymous):

Therefore it can't be "D", option D says 1:3. Meaning it's B , correct?

OpenStudy (dumbcow):

what no, B says lengths are equal, which is not true

OpenStudy (anonymous):

Why would it be D if the ratio is 1:3 and not 3:1?

OpenStudy (dumbcow):

its same ratio just depends on the reference point big:small --> 3:1 small: big --> 1:3 either way the big is always 3 times the length of small

OpenStudy (anonymous):

OH! so it Could only be -> D?
