OpenStudy (alexandervonhumboldt2):
do you know why DB=DC? hint: D is a midpoint
OpenStudy (alexandervonhumboldt2):
@pooja195

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

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

#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 ;)

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? :)
