If the rectangle is dilated using a scale factor of 3 and a line is drawn through the center of the new dilated figure, what relationship will the new line have with line EF? Explain your reasoning using complete sentences?

Answer 1

yo

Answer 2

@annabolton do u still want help with this cuz il try

ok

Answer 9

good.. but the line probably doesn't stick outside of the rectangle.. right? :P

anyhoo.. now imagine blowing up this rectangle 3 times the size.. what do you think will happen to the length of ef?

Answer 10

it gets smaller in comparison to the rectangle

Answer 11

huh?!.. you are asked to compare the new line(after scaling) with the old line(before scaling)

Answer 12

Its longer I guess im sorry im really bad at geometry

Answer 13

see i drew it for you..
if the rectangle sides got 3 times bigger

what do you think will that middle line be?

if A'B' is three times AB
what can you say about E'F' in comparison with EF?
