No!

- jim_thompson5910

I'm assuming the first two lines were given on another sheet or somewhere else (I don't see them given on this image attachment)

Yes I talked to my teacher about the sheet and she gave me those.

- jim_thompson5910

reason 6 is incorrect

- jim_thompson5910

so is reason 7

- anonymous

How should I go about fixing those?

- jim_thompson5910

you'll need to use a triangle congruence property for reason 6

- jim_thompson5910

triangle congruence properties
SSS
SAS
ASA
AAS

- anonymous

How would I know which one, when none of them are marked?

- jim_thompson5910

|dw:1449875850667:dw|

- jim_thompson5910

these two angles are congruent
|dw:1449875876681:dw|
this is line 4 of your proof

- jim_thompson5910

so are these two angles
|dw:1449875901498:dw|
this is line 5

- jim_thompson5910

line 3 says we have these two congruent segments
|dw:1449875942075:dw|

So what I get from this is it would be aas, but my only thing about that is my teacher earlier when she was helping me with it hinted that it was one of her favorite things with triangles, which she has stated before is cpctc.

- anonymous

If would be so kind would you be able to explain why cpctc wouldn't work here, just so I understand

- jim_thompson5910

cpctc will be used on reason 7
if you know 2 triangles are congruent, then all the corresponding pieces that pair up must be congruent

- jim_thompson5910

it's like saying
if house A = house B (ie the two houses are the same)
then door A = door B (the doors of each house are the same)

- anonymous

Ok I see that, so what you are saying is that 6 is aas due to my previous reasons giving me whether or not they (parts) are congruent and 7 would be cpctc, because they are congruent parts of the congruent triangles?

- jim_thompson5910

cpctc = corresponding parts of congruent triangles are congruent

- jim_thompson5910

6 = aas property of congruence
7 = cpctc
correct

- anonymous

Ok thank you very much, could you help me with a variation of this? please

- jim_thompson5910

sure

- anonymous

Now this I'm not sure at all

one moment

- anonymous

Thats fine take your time I really appreciate any help your willing to give me.

- jim_thompson5910

ok so before we knew that
angle G = angle I
what other two angles are equal?

- anonymous

Angle F and Angle H

- jim_thompson5910

yes, what other two angles (there's one more pair)

- anonymous

The vertical angles that form because of J?

- jim_thompson5910

yes, we list 3 letters to name an angle
example: angle GJH
|dw:1449877113175:dw|

- jim_thompson5910

angle GJH = angle IJF because they are vertical angles
|dw:1449877164612:dw|

- anonymous

So number 5 would be < GJH =IJF then reason would be Vertical Angles?

- jim_thompson5910

yes

- anonymous

I knew that there was vertical angles in here just didn't know when they would come into play, and how about the reason for number 6?

- jim_thompson5910

it won't be aas but it will be very similar

- anonymous

Would it be ASA?

- jim_thompson5910

yep
|dw:1449877579574:dw|

- jim_thompson5910

|dw:1449877600991:dw|

- jim_thompson5910

|dw:1449877628788:dw|

- jim_thompson5910

aas and asa are similar but the key difference is that with asa, the side is between the two angles

- anonymous

Yes I understand that :) Thank you very much for helping me out I appreciate it because it was kinda stuck on the bonus and of course in part a I had two wrong, but thank you for taking the time to explain it and work it through with me, thank you so much, also I don't know if you care about this but would you like for me to fan you?

- jim_thompson5910

I don't mind either way to be honest, so I'll leave that up to you to decide. I'm glad I could help out though and that it's making more sense.

- anonymous

Yes I understand it much more now, again thank you and have a nice night.

- jim_thompson5910

you're welcome and you too
