## KatherinePierce1864 2 years ago 1. Which line segment is parallel to GE? a) DH b) KI<-my answer c) FG d) HI 2. Which two line segments are skew? a) DE and GE b) EI and GK c) GK and DH<-THIS ONE d) HI and DF<--OR THIS ONE?

3. ganeshie8

first question is right

4. ganeshie8

for the second question, only one option has skew lines pair.

5. ganeshie8

GK and DH <-- are NOT skew lines, why ?

6. KatherinePierce1864

Because they do line up right? So it would be D then?

7. ganeshie8

thats right ! we can draw a plane thru that corner, and GK and DH line up on that plane. so they are not skew lines. D = \(\checkmark\)

8. KatherinePierce1864

You know I thought that at first :P I just wasn't sure.

9. KatherinePierce1864

Thank you!

10. ganeshie8

np... yw :)

@ganeshie8 Do you think you can help me one more time?

12. ganeshie8

sure, post.. .

3. Which angle corresponds to <7? (1 point) a) <1 b) <3 c) <4 d) <6 4. Which pair of angles are same-side interior angles? (1 point) <1 and <5 <3 and <6 <4 and <6 <3 and <5

14. KatherinePierce1864

My answers are: 1. C 2. B

15. ganeshie8

imagine we slide the top line slowly down, and overlap it over bottom line

16. ganeshie8

then, <3 falls on <7, right ?

19. ganeshie8

<1 corresponds to <5 <3 corresponds to <7

20. KatherinePierce1864

21. ganeshie8

^right

22. KatherinePierce1864

Okay, that makes sense. What about the other question? Did I get that one wrong as well?

23. ganeshie8

the other question has two options which are correct

24. ganeshie8

|dw:1349404973325:dw|

25. ganeshie8

<4 and <6 is one pair of same-side-interior angles.

26. ganeshie8

|dw:1349405026394:dw|

27. ganeshie8

<3 and <5 is another pair of same-side-interior angles.

28. ganeshie8

both last two options are correct equally.

29. KatherinePierce1864

So I was right? :)

30. ganeshie8

oy you said it was B, hmm ;p

31. KatherinePierce1864

Thank you!

32. ganeshie8

good luck next time :)
