i think its line 6

OpenStudy (anonymous):

Thanks! I already answered this as 1 and it was incorrect, but now I'm retaking the test w/ new questions :/ Can you explain why it was 6 though, I'd love to know for future reference

OpenStudy (mathmath333):

it should be \[\Delta ABC \approx = \Delta EDF\]

OpenStudy (mathmath333):

the name \[\Delta EFD\] was an error i think

OpenStudy (mathmath333):

\[side AC \approx =side EF\]
