1) a reflection over the y-axis, followed by a reflection over the x-axis

2. beckiiXbeckii

That sounds correct to me

3. some_someone

oh, ok I just need 2) & 3) I think...

4. yisrael11

Yes, that is correct

5. yisrael11

10. some_someone

i rally need help cause i don't get it.. i got confused!!! :( so i would really appreciate the help from anyone right now!!!

11. goformit100

ok

12. dpaInc

|dw:1338667087210:dw| imagine if C was on that firs line... what would the distance be then between C and C'' ?

13. some_someone

is it: Distance between k and m = 2.6 inches Distance from C to the distance from C" to m = 2.6 inches because this is a translation. 2.6 inches + 2.6 inches = 5.2 inches 5.2 inches or not???

14. dpaInc

two reflections over separate parallel lines = translation

15. some_someone

wht does thts mean dpalnc???

16. some_someone

so what is it then??? i have no clue then!!!

17. dpaInc

|dw:1338667406829:dw| oh, yeah... your right... 5.2

18. dpaInc

i'm bad with these transformations.... :(

19. some_someone

so it is 5.2???

20. dpaInc

wait... lemme double check..

21. some_someone

can you help me with number "3)"??? i would really appreciate it!!

22. dpaInc

yes it is... :)

23. AccessDenied

|dw:1338667559696:dw| If maybe that representation makes sense, to see why its 5.2: we have the 2.6 in the center, and then the two segments that compose 2.6 on the outside to make another 2.6.

24. some_someone

@AccessDenied so it is 5.2??? right!!!

25. dpaInc

|dw:1338667679753:dw|

26. some_someone

@dpaInc & @AccessDenied so its settled... the answer is 5.2???!!! right???

27. AccessDenied

Yes. lol as for the next one, I'd have to think about that one.

28. some_someone

ok, but please do help me :) i would realllyyy appreciate ur help and dpalnc's help tooo!!! alot!!!

29. dpaInc

|dw:1338668173430:dw|

30. dpaInc

isn't it obvious now? go get from A to A''?

31. dpaInc

**to get

32. some_someone

is it right wht i got???

33. dpaInc

"length of CC'' = 110 degrees" ?? when did they start using degrees to measure length?

34. dpaInc

i gotta read up more.. :)

35. some_someone

if uur doing 3), it says Find the angle of rotation that maps A onto A". so i guess it says to find it in degreess?? right???

36. dpaInc

yep... you seem stressed... take a break... have a donut...:)

37. some_someone

hahaha, yeah sort of because i gave beeen working on these problems for a long period of time. and the hw is due tomorrow!!! so yeah.. so wht is the answer for |dw:1338668638807:dw|

38. dpaInc

this shows that to get from A to A'' , just double the angle between the two intersecting lines of reflection... :) we didn't give you directly that the angle of rotation is twice that... i thought this clearly shows how much you should rotate to get to where you want to...|dw:1338668814266:dw|
