## cbrusoe 3 years ago The figure below shows Quadrilateral CDBE inscribed in a circle with center A. http://go.flvs.net/courses/1/flvs_57_3641_12676/ppg/respondus/pool_Geom_3641_1005_03/image0014e9880ac.gif

The paragraph proof with missing statement proves that its opposite angles are supplementary. Which statement can be used to fill in the blank space? Given that CDBE is a quadrilateral inscribed in a circle with center A, ∡DCE and ∡DBE are inscribed angles. Since the measure of an inscribed angle is one-half the measure of its intercepted arc, __________________________________ and ∡DBE is half of arc DCE. Since arc DBE and arc DCE add up to the whole circle, or 360 degrees, the total of ∡DCE and ∡DBE must be half of 360, or 180 degrees. Therefore, they are supplementary. By the definition of a quadrilateral, all interior angles must add to 360. Therefore, the other two angles must also be supplementary. Answer ∡CBE is half of arc DCE ∡EDC is half of arc ECD ∡DCE is half of arc DBE ∡DBE is half of arc DCE

Did you get the answer to this?

3. cbrusoe

hey yeahh sorry i dont remember if it was right or not tho hold on. did you still need the answer?

4. thismanhere

Yes. I'm working on that assignment right now, and would love some help. Thanks

5. thismanhere

The Circle Proof assignment.

6. cbrusoe

ok i got all of those right so for this one the answer was --arc DBE and arc DCE

7. thismanhere

you got the all right? first time, i only got one

8. cbrusoe

no aha i only got 2 right the first time i think the second time i used the first one to correct myself tho nd got them all right

9. thismanhere

10. thismanhere

what about the one with the two-column proof with the circle?

11. thismanhere

asking which statement to be used to fill in the blank

12. cbrusoe

lol well i got them all right the second time so i can help you as much as i can at least and the answer for that one i had as GK + GJ = JK

13. thismanhere

these are my answers: GI = FI GK = FI AJ = AH GH = FJ

14. thismanhere

15. cbrusoe

mmmm idk post the question nd pic. i think our questions are kinda diff. cuz im going off of my second attempt so not all of them are exactly the same as thee questions for the first attempt so

16. thismanhere

i posted a picture of the question and answers above.

17. cbrusoe

i see it now hold on

18. cbrusoe

yeahh im not sure but i just asked for some help from this guy he is rlly good at this stuff so hopefully he can help some

19. thismanhere

Our charts should look the same, just have different pieces missing.

20. cbrusoe

Well, yeah, but yours asks for the square root postulate, where as mine asked for the segment addition postulate.

21. thismanhere

if you had the segment addition postulate missing, it should have the square root postulate one already filled in with the answer i'm looking for

22. cbrusoe

ooh duh sorry.... its GK = FI

23. thismanhere

okay one more

24. thismanhere

thank you very much by the way! you're such a good help :)

Jennifer made the following measurements: CF = 8 cm, DF = 4 cm, EF = 7 cm and BF = 3 cm. The following proof shows that Jennifer’s measurements were wrong. What is the missing reason in the proof?

27. cbrusoe

is this in the same assignment?

28. thismanhere

Yes.

29. thismanhere

30. thismanhere

choices: Multiplication Property of Equality Simplify Two Secants from the Same Point Substitution

31. cbrusoe

ok i see it .i had simplify to fill in for the blank next to 32 = 21

32. thismanhere

I'm looking for this one: 8 · 4 = 7 · 3

33. thismanhere

the one above 32=21

34. cbrusoe

mmk it's substitution

35. thismanhere

ah thank you so much again! :)

36. cbrusoe

aha np =)

37. thismanhere

you do FLVS too?

38. cbrusoe

yep it's my first year though. i will be back in hs nxt yr i hope tho

39. thismanhere

i'll message you. :D

40. cbrusoe

ok =D
