Question

PLEASE HELP FAST!! :)

Answer 1

@Bookworm14 do you think you can help?

Answer 2

im looking now :)

Answer 3

thank you!

Answer 4

So I am super new at this, and I would NOT take my word for it, but if I HAD to guess I would pick B @jim_thompson5910 what do you think?

Answer 5

yeah i b is the one i kind of thought of first but I'm so bad at geometry i was like ok i better ask someone haha

Answer 6

I'm looking it over now

Answer 7

ok cool :)

Answer 8

I agree. The other choices are wrong so they're eliminated. Only B is left over.

What Nick should have done was use PD = PC in his first statement. If he did that, then his proof would be pretty solid

Answer 9

So yes, B is the correct answer

Answer 10

ok awesome, thank you both so much! I appreciate it :)

Answer 20

and okay sounds good! thanks!! :)

Answer 21

let me see

Answer 22

aww haha thanks @Bookworm14 :) if u need help with anything on yours, let me know! Im not good at math at all but i'd be happy to try helping you out :)

Answer 23

ok

Answer 24

ok I spotted the error. It's all about how you order the letters when it comes to similarity

Answer 25

notice how triangle ABC has the 90 degree angle at the center, so does triangle BDC

Answer 26

but when it comes to triangle ABD, we run into a problem

Answer 27

if you simply flip D and B and say triangle ADB, then it fixes the issue

Answer 28

so that's why the answer is actually choice B

Answer 29

Rule:

If you claim that
triangle ABC is similar to triangle DEF

then this means
angle A = angle D
angle B = angle E
angle C = angle F

so that's why order matters

Answer 30

aahh i see, that makes perfect sense, thanks!

Answer 31

you can also look at the proportion they form in reason4 and notice how it will never yield to AB^2 = AC*AD. So that's another red flag

Answer 32

yeah, i see that now! thanks so much jim
