im about to put the questions.

Please pay attention in class, so you don't have to ask for your entire homework answer.

- 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

Awesome! Maybe when were done I wont hate them as much.

- 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

Sure, sorry, mom called haha

- I_need_help_please

oh okay. lol

- 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

- sleepyjess

Are we looking at the same problem?

- I_need_help_please

im looking at number 1.

- I_need_help_please

oh wait.. i get what your saying.. another given is b=~ e A=~D

- sleepyjess

There is nothing labeled C in #1 though

- 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

Oh wait, there is a C. Shows how blind I am :)

- I_need_help_please

okay
so 2. is A=~ D

- sleepyjess

Yep, and we just figured out that A \(\cong\) D is a given, so that will be 3

- I_need_help_please

okay

- sleepyjess

Now, do you know the triangle theorems such as side angle side, angle side side, etc?

- 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

would this be congruent by the angle angle side theorem?

- 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.

- I_need_help_please

Oh okay i see. I always confuse myself.

- 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

So, for number 2, 1 and 2 for the staments are PQ=~RS and ,PQS=~RSQ?

- sleepyjess

Yes!

- I_need_help_please

and number 3's reason is the adjacent angles postulate or theorem?

- 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

yes.

- sleepyjess

That's what we're going to use for #3, QS = QS, reflexive property of congruence

- sleepyjess

Basically saying, x = x

- I_need_help_please

okay
and number 4 is SAS?

- sleepyjess

Yes!

- I_need_help_please

will the last one always be one of the SAS ASA or one of those?

- sleepyjess

Yep

- I_need_help_please

okay

- I_need_help_please

for number 3, i fill in all of the given things? and then on number four put ABC=~DEF?

- sleepyjess

Yes, I think they made a typo haha

- I_need_help_please

typo on what?

- sleepyjess

Prove ABD \(\cong\) DEF

- sleepyjess

But ABD isn't a triangle

- I_need_help_please

oh yeah i see

- sleepyjess

You're catching on to proofs really quickly :)

- I_need_help_please

yeah im excited thanks:) im not sure why i just could never get it.

- I_need_help_please

For number 4 do the two givens then number 3 is MO=~ OM 4. ASA or AAS?

- sleepyjess

I think you've got #4 figured out already ;)

- 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

Close for number 3, it would either be MO \(\cong\) MO or OM \(\cong\) OM

- I_need_help_please

oh okay.

- I_need_help_please

what about for 4. i think it would be AAS

- sleepyjess

and for proving congruence, just remember to look at what is directly in a row
|dw:1449678966242:dw|

- sleepyjess

Yep, AAS :)

- 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

Correct :)

- 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 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

Okay, if AE bisects BD, then DC \(\cong\) CB

- I_need_help_please

so write DC =~CB?

- sleepyjess

Yes

- I_need_help_please

i dont get 4.

- sleepyjess

4, do you know what vertical angles are?

- I_need_help_please

yes|dw:1449679514188:dw|

- sleepyjess

Vertical angles are congruent, ACB and DCE are vertical angles

- I_need_help_please

so for four put vertical angles theorem

- I_need_help_please

or definition of vertical angles?

- sleepyjess

I would put definition of vertical angles

- I_need_help_please

okay and for 5 AAS?

- sleepyjess

Question 6, I'm honestly not sure

- sleepyjess

Yes

- I_need_help_please

is that right for 5? AAS?

- I_need_help_please

okay

- sleepyjess

Yes, question 5 is correct

- I_need_help_please

look at number 4 on 6. there is no ACB or DCE..

- sleepyjess

Yes, that's partially why I'm confused about it

- sleepyjess

Is this homework?

- 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

would 3 be verticle angles?

- I_need_help_please

or alternate interior angles?

- sleepyjess

I know it's not vertical angles, I think you're right with alternate interior

- I_need_help_please

okay. now to 7 i think there is another typo on 4.

- I_need_help_please

i think DEF needs to be DEC

- 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

I think you're right on that typo :)

- I_need_help_please

what are the reasons though for 3 and 4 im pretty sure 5 is SAS

- sleepyjess

Now 3, is going to be vertical angles I'm pretty sure

- 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

yes but i dont understand it. 4 is SAS or 5?

- sleepyjess

4 is SAS because 4 is proving the triangles

- I_need_help_please

okay

- sleepyjess

Then 5 is CPCTC because we're just proving the angles

- I_need_help_please

i get cpctc i just looked it up. that is 5 right/

- I_need_help_please

okay

- I_need_help_please

#4 for question 8

- sleepyjess

Definition of a midpoint

- I_need_help_please

okay then 5 and 6.

- I_need_help_please

is I the cooresponding angle?

- I_need_help_please

or H and I

- sleepyjess

We know it has to make SAS congruence for the next one, so I'd go with

- I_need_help_please

6. GHI =~ JIK?

- sleepyjess

Yep

- I_need_help_please

and 7?

- 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

4 on question 9

- I_need_help_please

would that be cooresponding?

- sleepyjess

Since OP bisects MN, that mean MO = ON

- sleepyjess

and OP = OP

- sleepyjess

Wait, I'm a step ahead

- I_need_help_please

yeah whats four?

- sleepyjess

We need an angle >_<

- I_need_help_please

i shouldve left 15 minutes ago but im trying to get this done.. were almost done..

- I_need_help_please

yeah lol

- sleepyjess

I would go with SAS for #4, that's the only thing I can think of

- I_need_help_please

what about 5?

- I_need_help_please

and both 2's for question 10

- sleepyjess

MO = ON, definition of a bisector

- sleepyjess

TU = TU, reflex prop of cong

- sleepyjess

Does that make sense?

- I_need_help_please

yes

- 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

Okay, now HL theorem requires triangles to be congruent, so statement would be SUT \(\cong\) VTU

- I_need_help_please

i got that already.

- sleepyjess

Then TS \(\cong\) UV :)

- I_need_help_please

yep. Thanks for all your help:D

- sleepyjess

Hopefully you understand proofs better now :)
It sure looks like you do ^_^

- sleepyjess

No problem!
