HELP! **PROOF** I GIVE MEDALS ;) finish the proof that ∠WZX≅∠YXZ 1)WZ≅YX----->____?___ 2)_____?___---->Given 3)_____?___---->Reflexive Property of Segment Congruence 4)ΔWXY≅ΔYZX----->______?____ 5)_______?___------>Corresponding parts of ≅ Δ are ≅

OpenStudy (anonymous):

@mathstudent55 could u help me on this one?

hero (hero):

Do you have any ideas on what the possible reasons are for each statement?

OpenStudy (anonymous):

for some of them

hero (hero):

Okay, what do you have for the 1st one?

OpenStudy (anonymous):

would it be by SAS (side angle side)

OpenStudy (anonymous):

i no the given..WX=YZ and WZ=XY

OpenStudy (anonymous):

i ment congruent

OpenStudy (mathstudent55):

What statement do you have for step 3?

OpenStudy (anonymous):

Reflexive property of segment cogruence

OpenStudy (mathstudent55):

That's the reason which is supplied. What is the statemtn you put in the blank in step 3?

OpenStudy (anonymous):

ooh sorry misunderstood...WX is congruent to ZY

OpenStudy (mathstudent55):

Isn't that the statement of step 2?

OpenStudy (anonymous):

I don't kno??? is that wat is given??

OpenStudy (mathstudent55):

You didn't show the "given" or the "prove" of this proof, so we need to guess which reasons are given. Didn't this proof come with a figure (which you showed) and a "given" and a "prove"?

OpenStudy (anonymous):

no it just gave me the pic and the reasons and statements I gave above....Fishish the proof that ∠WZX≅∠YXZ by filling in the missing statements and reason

OpenStudy (mathstudent55):

Ok. Then let's do it.

OpenStudy (anonymous):

ok sounds good to me :)

OpenStudy (mathstudent55):

WZ and YX are shown to be congruent in the figure. So reason 1 is: Given.

OpenStudy (anonymous):

So their can be to givens??

OpenStudy (mathstudent55):

Yes. There can be many givens. Since reason 2 is "Given" we look in the figure for the other given info.

OpenStudy (mathstudent55):

The other given ifo you can read off the figure is placed in statement 2. Statement 2. WX is congr. to YZ

OpenStudy (anonymous):

ok I understand

OpenStudy (mathstudent55):

1)WZ≅YX -----> Given 2)WX≅YZ -----> Given 3)_____?___---->Reflexive Property of Segment Congruence 4)ΔWXY≅ΔYZX----->______?____ 5)_______?___------>Corresponding parts of ≅ Δ are ≅

OpenStudy (anonymous):

woult 3 be Triangle WXY is congruent to triangle YXZ

OpenStudy (mathstudent55):

We have lines 1 and 2 done. Now we work on line 3. We need a statement for step 3. The reason of step 3 is reflexive. That means something is ciongruent to itself.

OpenStudy (mathstudent55):

Step 4 is the triangles are congruent. Step 3 is one more step leading to the triangles being congruent.

OpenStudy (mathstudent55):

Which ways do you know of proving two triangles congruent?

OpenStudy (anonymous):

Triangel WXZ is congruent to YXZ 40base angles theorem

OpenStudy (anonymous):

I ment 4)base angle theorem

OpenStudy (mathstudent55):

ASA, AAS, etc. Do you know other methods in addition to AAS, and ASA?

OpenStudy (anonymous):

yes

OpenStudy (mathstudent55):

Can you list them?

OpenStudy (anonymous):

do u meant for the anwer or just list them all

OpenStudy (mathstudent55):

I asked if you know methods of proving triangles congruent. I already listed AAS and ASA. Do you know other methods, and if so, can you list them?

OpenStudy (mathstudent55):

List them all. Not just what we need here.

OpenStudy (anonymous):

ooh SSS SAS HL ASA AAS

OpenStudy (mathstudent55):

Good.
