anonymous one year ago Reasons In Geometric Proofs: Please Help Me! Which postulate can be used to prove triangle QTR is congruent to triangle STR a. SAS b. AAS c. Not Congruent d. ASA

1. anonymous

2. SolomonZelman

you can see (based on the diagram) $${\rm QT}= {\rm ST}$$ $$\angle {\rm Q}=\angle {\rm S}$$ and the two triangles share a common side $${\rm TR}$$.

3. SolomonZelman

-:(

4. SolomonZelman

name each of the congruences that I mentioned respectively, as either A or S.

5. SolomonZelman

what does A and S stand for?

6. anonymous

I Got SAS! @SolomonZelman

7. SolomonZelman

Yes, SAS is right

8. anonymous

Omg Thank You, You Explain It Better And Make It Easier!

9. SolomonZelman

Nice to hear that; tnx for the complement and you are always welcome...

10. anonymous

I Have One More That Is Just Like This One, May You Please Explain It To Me? :)

11. anonymous

Which postulate can be used to prove that the triangles are congruent? A. not congruent B. SSA C. HL D. SAS

13. anonymous

I Know For A Fact It Is Not C Or A

@UsukiDoll

15. UsukiDoll

let me think.. it's been a while.. but I have studied some of the theorems.

16. UsukiDoll

what does HL stand for?

17. anonymous

Hypotenuse Leg,

18. UsukiDoll

hmmm I don't remember a theorem with that.

19. UsukiDoll

so it's either the side side angle theorem or the side angle side theorem.

20. anonymous

Yes because the hypotenuse leg is incorrect, so it is one of those 2, do you have an idea of what it can be?

21. UsukiDoll

xD! there is no SSA postulate spell SSA backwards xD

22. anonymous

retrice

23. anonymous

lol, so SAS?

24. UsukiDoll

yeah... since that theorem doesn't exist. We just side angle side theorem and that one exists.

25. UsukiDoll

The Side Angle Side postulate (often abbreviated as SAS) states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.

26. anonymous

EXCUSE THE OTHER WORD LOL. and okay thank you! @UsukiDoll

27. UsukiDoll

tbh, that was the first time I heard SSA. Don't remember it in my lectures, but SAS was used a lot so I know that existed.

28. SolomonZelman

how about an A.S.S postulate ?

29. SolomonZelman

excuse me:)

30. UsukiDoll

doesn't exist ^

31. SolomonZelman

Angle Side Side , in essence equivalent to Side Angle Side

32. UsukiDoll

my professor used SAS a lot last semester, but there is no retriceor SSA

33. anonymous

well i submitted my assignment and both answers were wrong :(

34. UsukiDoll

O_O! say what?! Was I just censored just now

35. SolomonZelman

(of course I am kidin) I used retricein class a bunch of times

36. UsukiDoll

I hope I do not get a warning from OS XD

37. UsukiDoll

hey have you guys seen the OS commercial on youtube?

38. SolomonZelman

the $$\rm A {\tiny~}S {\tiny~} S$$ postulate lmao

39. SolomonZelman

bye:)
