@Hero

Answer 4

good thing you spotted that ...

Answer 5

ΔDEF/ΔABC = 1/2

Answer 6

it says def to abc
and i did the ratio for abc to def
so it is just 1/2 by taking its reciprocal

Answer 7

Yay! I gotta stop doubting myself. thanks you guys.

Answer 8

I was demonstrating a way to do it so that people don't get it backwards.

Answer 9

If you start off with ΔDEF/ΔABC equals .... then you should be able to correspond the right numbers without mixing them up.
