Please pay attention in class, so you don't have to ask for your entire homework answer.
I_need_help_please
  • I_need_help_please
I do pay attention in class. I just have never understood proofs and always have trouble. Im asking for help not answers.

I love proofs! We'll do this together!
I_need_help_please
  • I_need_help_please
Awesome! Maybe when were done I wont hate them as much.
I_need_help_please
  • I_need_help_please
Can we start on the first question? What im confused about with proofs is i get confused with all of the terms and what it could be and i usually dont pick the right postulate or definition.
sleepyjess
  • sleepyjess
Sure, sorry, mom called haha
I_need_help_please
  • I_need_help_please
oh okay. lol
sleepyjess
  • sleepyjess
Okay, we have AB is congruent to DE, and that's given. What's another given that's not already on the proof?
I_need_help_please
  • I_need_help_please
sleepyjess
  • sleepyjess
Are we looking at the same problem?
I_need_help_please
  • I_need_help_please
im looking at number 1.
I_need_help_please
  • I_need_help_please
oh wait.. i get what your saying.. another given is b=~ e A=~D
sleepyjess
  • sleepyjess
There is nothing labeled C in #1 though
sleepyjess
  • sleepyjess
Okay, there we go. A \(\cong\) D is in the next step, so we know that B \(\cong\) E has to be in the second step
sleepyjess
  • sleepyjess
Oh wait, there is a C. Shows how blind I am :)
I_need_help_please
  • I_need_help_please
okay so 2. is A=~ D
sleepyjess
  • sleepyjess
Yep, and we just figured out that A \(\cong\) D is a given, so that will be 3
I_need_help_please
  • I_need_help_please
okay
sleepyjess
  • sleepyjess
Now, do you know the triangle theorems such as side angle side, angle side side, etc?
I_need_help_please
  • I_need_help_please
what is the reason that the two triangles are congruent? I think i know them but not very well. I get mixed up with all of them
I_need_help_please
  • I_need_help_please
would this be congruent by the angle angle side theorem?
sleepyjess
  • sleepyjess
That's fine :) We have an angle, a side then another angle, so how we figure this out, is just put them in order of where they are. |dw:1449678033010:dw|
I_need_help_please
  • I_need_help_please
Oh okay i see. I always confuse myself.
sleepyjess
  • sleepyjess
haha, I used to hate proofs, but now I love them because I've had some time to process all of the information needed :)
I_need_help_please
  • I_need_help_please
So, for number 2, 1 and 2 for the staments are PQ=~RS and ,PQS=~RSQ?
sleepyjess
  • sleepyjess
Yes!
I_need_help_please
  • I_need_help_please
and number 3's reason is the adjacent angles postulate or theorem?
sleepyjess
  • sleepyjess
Now for #3 in question 2, do you know what the reflexive property is? Basically a = a, or x + y = x+y
I_need_help_please
  • I_need_help_please
yes.
sleepyjess
  • sleepyjess
That's what we're going to use for #3, QS = QS, reflexive property of congruence
sleepyjess
  • sleepyjess
Basically saying, x = x
I_need_help_please
  • I_need_help_please
okay and number 4 is SAS?
sleepyjess
  • sleepyjess
Yes!
I_need_help_please
  • I_need_help_please
will the last one always be one of the SAS ASA or one of those?
sleepyjess
  • sleepyjess
Yep
I_need_help_please
  • I_need_help_please
okay
I_need_help_please
  • I_need_help_please
for number 3, i fill in all of the given things? and then on number four put ABC=~DEF?
sleepyjess
  • sleepyjess
Yes, I think they made a typo haha
I_need_help_please
  • I_need_help_please
typo on what?
sleepyjess
  • sleepyjess
Prove ABD \(\cong\) DEF
sleepyjess
  • sleepyjess
But ABD isn't a triangle
I_need_help_please
  • I_need_help_please
oh yeah i see
sleepyjess
  • sleepyjess
You're catching on to proofs really quickly :)
I_need_help_please
  • I_need_help_please
yeah im excited thanks:) im not sure why i just could never get it.
I_need_help_please
  • I_need_help_please
For number 4 do the two givens then number 3 is MO=~ OM 4. ASA or AAS?
sleepyjess
  • sleepyjess
I think you've got #4 figured out already ;)
I_need_help_please
  • I_need_help_please
im just going to type my answers so you can check becuase i can do it but im still a little doubtfull on some of my answers.
sleepyjess
  • sleepyjess
Close for number 3, it would either be MO \(\cong\) MO or OM \(\cong\) OM
I_need_help_please
  • I_need_help_please
oh okay.
I_need_help_please
  • I_need_help_please
what about for 4. i think it would be AAS
sleepyjess
  • sleepyjess
and for proving congruence, just remember to look at what is directly in a row |dw:1449678966242:dw|
sleepyjess
  • sleepyjess
Yep, AAS :)
I_need_help_please
  • I_need_help_please
okay cool. thats what i thought but ,y other thoughts were if we go clockwise it would be ASA but those arent as close as the AAS
sleepyjess
  • sleepyjess
Correct :)
I_need_help_please
  • I_need_help_please
for five 1 is given and 2 is ae bisects bd . for number 3, it says the reason is definition of bisect so what would i put for the statement?
I_need_help_please
  • I_need_help_please
I only have 10 minutes left untill i have to leave. Im going to fill in the givens on all of the problems becuase i know i have that part and try to see what im sure about on my own so i can only ask about the stuff im confused on.
sleepyjess
  • sleepyjess
Okay, if AE bisects BD, then DC \(\cong\) CB
I_need_help_please
  • I_need_help_please
so write DC =~CB?
sleepyjess
  • sleepyjess
Yes
I_need_help_please
  • I_need_help_please
i dont get 4.
sleepyjess
  • sleepyjess
4, do you know what vertical angles are?
I_need_help_please
  • I_need_help_please
yes|dw:1449679514188:dw|
sleepyjess
  • sleepyjess
Vertical angles are congruent, ACB and DCE are vertical angles
I_need_help_please
  • I_need_help_please
so for four put vertical angles theorem
I_need_help_please
  • I_need_help_please
or definition of vertical angles?
sleepyjess
  • sleepyjess
I would put definition of vertical angles
I_need_help_please
  • I_need_help_please
okay and for 5 AAS?
sleepyjess
  • sleepyjess
Question 6, I'm honestly not sure
sleepyjess
  • sleepyjess
Yes
I_need_help_please
  • I_need_help_please
is that right for 5? AAS?
I_need_help_please
  • I_need_help_please
okay
sleepyjess
  • sleepyjess
Yes, question 5 is correct
I_need_help_please
  • I_need_help_please
look at number 4 on 6. there is no ACB or DCE..
sleepyjess
  • sleepyjess
Yes, that's partially why I'm confused about it
sleepyjess
  • sleepyjess
Is this homework?
I_need_help_please
  • I_need_help_please
i can just cross it out and put a note on the side that there is none. lets just do the problem with out 4.
I_need_help_please
  • I_need_help_please
would 3 be verticle angles?
I_need_help_please
  • I_need_help_please
or alternate interior angles?
sleepyjess
  • sleepyjess
I know it's not vertical angles, I think you're right with alternate interior
I_need_help_please
  • I_need_help_please
okay. now to 7 i think there is another typo on 4.
I_need_help_please
  • I_need_help_please
i think DEF needs to be DEC
sleepyjess
  • sleepyjess
Okay, well it's kind of obvious now that the first 2 things are most likely going to be given, so we know that
sleepyjess
  • sleepyjess
I think you're right on that typo :)
I_need_help_please
  • I_need_help_please
what are the reasons though for 3 and 4 im pretty sure 5 is SAS
sleepyjess
  • sleepyjess
Now 3, is going to be vertical angles I'm pretty sure
sleepyjess
  • sleepyjess
4 is SAS, that's where we're proving the triangles, 5, b \(\cong\) D, have you heard of Corresponding Parts of Corresponding Triangles are Congruent?
I_need_help_please
  • I_need_help_please
yes but i dont understand it. 4 is SAS or 5?
sleepyjess
  • sleepyjess
4 is SAS because 4 is proving the triangles
I_need_help_please
  • I_need_help_please
okay
sleepyjess
  • sleepyjess
Then 5 is CPCTC because we're just proving the angles
I_need_help_please
  • I_need_help_please
i get cpctc i just looked it up. that is 5 right/
I_need_help_please
  • I_need_help_please
okay
I_need_help_please
  • I_need_help_please
#4 for question 8
sleepyjess
  • sleepyjess
Definition of a midpoint
I_need_help_please
  • I_need_help_please
okay then 5 and 6.
I_need_help_please
  • I_need_help_please
is I the cooresponding angle?
I_need_help_please
  • I_need_help_please
or H and I
sleepyjess
  • sleepyjess
We know it has to make SAS congruence for the next one, so I'd go with
I_need_help_please
  • I_need_help_please
6. GHI =~ JIK?
sleepyjess
  • sleepyjess
Yep
I_need_help_please
  • I_need_help_please
and 7?
sleepyjess
  • sleepyjess
7, same as the last one, angle G and angle J are in the same spot on each triangle, so CPCTC
I_need_help_please
  • I_need_help_please
4 on question 9
I_need_help_please
  • I_need_help_please
would that be cooresponding?
sleepyjess
  • sleepyjess
Since OP bisects MN, that mean MO = ON
sleepyjess
  • sleepyjess
and OP = OP
sleepyjess
  • sleepyjess
Wait, I'm a step ahead
I_need_help_please
  • I_need_help_please
yeah whats four?
sleepyjess
  • sleepyjess
We need an angle >_<
I_need_help_please
  • I_need_help_please
i shouldve left 15 minutes ago but im trying to get this done.. were almost done..
I_need_help_please
  • I_need_help_please
yeah lol
sleepyjess
  • sleepyjess
I would go with SAS for #4, that's the only thing I can think of
I_need_help_please
  • I_need_help_please
what about 5?
I_need_help_please
  • I_need_help_please
and both 2's for question 10
sleepyjess
  • sleepyjess
MO = ON, definition of a bisector
sleepyjess
  • sleepyjess
TU = TU, reflex prop of cong
sleepyjess
  • sleepyjess
Does that make sense?
I_need_help_please
  • I_need_help_please
yes
I_need_help_please
  • I_need_help_please
Thank you so much i really really appreciate you rhelp. I have to go now.. I have 12 minutes to get ready to leave and usually take 30 lol but i got my math done.:D
sleepyjess
  • sleepyjess
Okay, now HL theorem requires triangles to be congruent, so statement would be SUT \(\cong\) VTU
I_need_help_please
  • I_need_help_please
i got that already.
sleepyjess
  • sleepyjess
Then TS \(\cong\) UV :)
I_need_help_please
  • I_need_help_please
yep. Thanks for all your help:D
sleepyjess
  • sleepyjess
Hopefully you understand proofs better now :) It sure looks like you do ^_^
sleepyjess
  • sleepyjess
