Anyone really good at Geometry? With like the Given and Prove?

OpenStudy (anonymous):

Yep.... what do you need help with?

OpenStudy (anonymous):

I love "I love Lucy" ! :D

OpenStudy (anonymous):

and hold on

OpenStudy (anonymous):

Thanks! :-)

OpenStudy (anonymous):

Supply the missing reasons to complete the proof. ASA; substitution SAS; Corresponding parts of are . AAS; Corresponding parts of are . ASA; Corresponding parts of are .

OpenStudy (anonymous):

I think it might be SAS but I'm not sure.

OpenStudy (anonymous):

It's ASA

OpenStudy (anonymous):

can you explain to me why

OpenStudy (anonymous):

Yes.... Let me draw a picture it will help

OpenStudy (anonymous):

and can you help me with the other 2? :)

OpenStudy (anonymous):

|dw:1354658642678:dw|

OpenStudy (anonymous):

Yes

OpenStudy (anonymous):

tatements Reasons 1. ∠A∠E and 2. ∠ACB ∠ECD 3. ΔACB ΔECD 4. 1. Given 2. Vertical angles are congruent 3. _?_ 4. _?_

OpenStudy (anonymous):

ASA; Corresponding parts of are . SAS; Corresponding parts of are . ASA; substitution AAS; Corresponding parts of are .

OpenStudy (anonymous):

So do you see the order of the angle, side, and angle. That's why it's ASA

OpenStudy (anonymous):

Ok: next one

OpenStudy (anonymous):

Yeah, now I see it.

OpenStudy (anonymous):

is this one the same as the other one?

OpenStudy (anonymous):

I don't know... I just started

OpenStudy (anonymous):

oh. well it's pretty similar to the other one. lol

OpenStudy (anonymous):

yep, wait is there one more thing, because there's only two pairs of congruent angles and there isn't enought info to confirm that the tiangles are congruent

OpenStudy (anonymous):

there's nothing missing. :/

OpenStudy (anonymous):

hmmm

OpenStudy (anonymous):

OK last one! c:

OpenStudy (anonymous):

Supply the reasons missing from the proof shown below. ASA; Corresponding parts of are . SAS; Reflexive Property SSS; Reflexive Property SAS; Corresponding parts of are .

OpenStudy (anonymous):

SAS

OpenStudy (anonymous):

|dw:1354659433420:dw|

OpenStudy (anonymous):

Because the order goes side, angle, and side

OpenStudy (anonymous):

does that make sense?

OpenStudy (anonymous):

how do I determine the second one? If it's corresponding or reflexive property?

OpenStudy (anonymous):

Corresponding because you already determined that the triangles are congruent

OpenStudy (anonymous):

Does that make sense? Just keep practicing and you'll get the hang of it.
