please give me the best answer.

Answer 1

Hi! Do you have any guesses?

Answer 2

two sides and included angle are congruent..so SAS

Answer 3

also ASA...since two angles aand included side are congruent

Answer 4

I agree with Krishnadas, and I hope you can see why. They are the only options in which the given information can be used to prove congruency. Angle-side-angle and side-angle-side....

Answer 5

That link might help in the future :)

Answer 6

You can also use AAS

Answer 7

so it's only SAS and ASA? @Krishnadas @theEric

Answer 8

yup

Answer 9

Yup, I think.

Answer 10

Wiat..

Answer 11

Wait*...

Answer 12

eric there are other ways to prove other than ours..LL theorem for right angles etc

Answer 13

Does LL apply? If it's what I think it is...

Answer 14

yes..right angles

Answer 15

LL is an option. So thihaaung would need that...

Answer 16

are the hypotenuses congruent?

Answer 17

LL is one answer..sure

Answer 18

They would have to be. It's like SAS.. Why is LL so special? Heheh...

Answer 19

LL,sss,SAS and ASA are sure then...lol

Answer 20

Is LA something like leg-angle that applies to right triangles too? Making it pretty much ASA?

Answer 21

yup

Answer 22

Well, the hypotenuse is not give, so SSS is out.

Answer 23

given*

Answer 24

LA is equivalent to ASA

Answer 25

Alright, thanks! :)

Answer 26

HA is also ruled out

Answer 27

*HL

Answer 28

Now you answered my question - you deserve two medals! And you're right, HL is out.

Answer 29

please don't confuse me. please give me the right answers. hehe
thank you ;)

Answer 30

Haha, they're here!

Answer 31

but @theEric LL equivalent to SAS

Answer 32

Very true, I agree, @Krishnadas .

Answer 33

:)

Answer 34

so what are left?

Answer 35

just SAS, ASA, LL? what else?

Answer 36

LL=SAS

Answer 37

Yep, all those.
LA, HL, and SSS are the only other possibilities. Any of those?

Answer 38

@thihaaung

Answer 39

@thihaaung me and @theEric will jus discuss abt it...and we will give you the final answer...okay?dont get confuced

Answer 40

Ah, if I were to give just the answer, which I only do after discussion, I would say

SAS, LL, LA, and ASA. You can use any one alone with only given information to prove that the triangles are congruent.

Answer 41

SAS,LL,LA,ASA

Answer 42

There is not enough information to use HL or SSS, so they can not be applied.

Answer 43

That is your answer, @thihaaung .

Answer 44

i thought so..but can we deduce from the pic that hypotenuses are congruent??

Answer 45

thanks y'all. those are right.

Answer 46

We can deduce that, but that information is not given. The question was specific about using only given information.

Answer 47

ok @thihaaung ..:D

Answer 48

oh oh..Never saw that..@theEric

Answer 49

Once we prove congruency, we can state that the hypotenuses are the same. Haha, got ya! Take care everyone!

Answer 50

:D
