Question

I NEED HELP WITH A PROOF!
PLEASE HELP ME!
SEE THE PICTURE ATTACHED!

Answer 1

for reason 2), it looks like the division property of equality is being used twice

Answer 2

since they divide both sides by BE and then divide both sides by BD to set up that proportion

Answer 3

ok, do you know 3 and 4?

Answer 4

it seems like step 3 is not necessary since you can use the SSS similarity theorem converse to go from 2 to 4 (and skip 3 entirely)

Answer 5

also, there isn't enough info to prove 3 anyway

Answer 6

OK, I can't understand completely. For reason 3 I should answer "not enough info", and for reason 4 I should answer what?

Answer 7

well that's my argument anyway, I could be missing something though

Answer 8

ok, thanks for your help.

Answer 9

you're welcome
