I need help with proofs can someone help with this? :) http://prntscr.com/9a1zec

pooja195 (pooja195):

@AlexandervonHumboldt2 @sleepyjess

pooja195 (pooja195):

Or anyone :P

OpenStudy (alexandervonhumboldt2):

first can be easily filled out

pooja195 (pooja195):

1) Given

OpenStudy (alexandervonhumboldt2):

yeah

OpenStudy (sleepyjess):

2 is ?

OpenStudy (alexandervonhumboldt2):

do you know why DB=DC? hint: D is a midpoint

OpenStudy (alexandervonhumboldt2):

@pooja195

pooja195 (pooja195):

2 is a given

OpenStudy (alexandervonhumboldt2):

noooooooooooo

OpenStudy (sleepyjess):

Correct

pooja195 (pooja195):

DB = DC

OpenStudy (alexandervonhumboldt2):

i wouldn't say that it is given, i would say that it is becasue AD is a bisector, but it is not given

pooja195 (pooja195):

._. im confused which is it?

OpenStudy (alexandervonhumboldt2):

i got confused too

OpenStudy (sleepyjess):

It is given, it shows that on the picture

OpenStudy (alexandervonhumboldt2):

hmm maybe yeah

OpenStudy (alexandervonhumboldt2):

ok lets go with given

OpenStudy (alexandervonhumboldt2):

what do you think for third?

pooja195 (pooja195):

3) <ABD & <ACD?

OpenStudy (alexandervonhumboldt2):

no

pooja195 (pooja195):

im confused ;-;

OpenStudy (alexandervonhumboldt2):

|dw:1449034564972:dw|

OpenStudy (sleepyjess):

Okay, you're right on #3

OpenStudy (sleepyjess):

Do you know #4?

pooja195 (pooja195):

no :/

OpenStudy (sleepyjess):

Whale, what are the 2 right angles?

pooja195 (pooja195):

ADB ADC

OpenStudy (sleepyjess):

Yep, so those are equal

OpenStudy (sleepyjess):

And that's #4, ADB=ADC

OpenStudy (sleepyjess):

#5, we're looking at a line to be able to prove the triangles (ABD and ACD) congruent

pooja195 (pooja195):

AD and Ad correct?

OpenStudy (sleepyjess):

Yes! Now what theorem do we prove ADB and ADC with?

pooja195 (pooja195):

SSS?

OpenStudy (sleepyjess):

Well, we can conclude that AB is congruent to AC, but we don't have that information quite yet, look at what we have, and don't make a bad word ;)

OpenStudy (sleepyjess):

There could actually be multiple answers for #6...

OpenStudy (sleepyjess):

I would use the one that includes the right angle if that helps at all :)

pooja195 (pooja195):

Ah ok thanks :D

OpenStudy (sleepyjess):

Got the rest now? :)
