Question

The figure below shows a transversal t which intersects the parallel lines AB and CD. http://go.flvs.net/courses/1/flvs_57_3641_12676/ppg/respondus/pool_Geom_3641_0908_14/image0044e7349ab.jpg prove that the sum of the measures of angle 1 and angle 2 is equal to 180°.

Answer 1

wow I had this same question!

Answer 2

hold on

Answer 3

haha mmk thanks!

Answer 4

1 SEC

Answer 5

kk

Answer 6

oh no I forgot abt u needing help srry

Answer 7

haha it's ok it's my last question for this assighnment

Answer 8

hey if you can't help it's ok

Answer 9

<1 and <3 are a linear pair, therefore their angle measure is equal to 180 degrees. <2 and <3 are alternate interior angles so their measures are also equal to 180 degrees. Does this help?

Answer 10

yes thanks! =)

Answer 11

wait are you sure angles 2 and 3 add up to 180 to?

Answer 12

Yep! They are alternate interior angles.

Answer 13

ok well thanks for the help!

Answer 14

Sure! I think we may be working on the same test. Is it for geometry at FLVS?

Answer 15

yepp!!

Answer 16

Fun! Good luck! I'm stuck on one of the questions :/

Answer 17

thanks i just finished i got like 8 wrong thats not including the fact idk what i got on the written responces so =p but yeahh post your questions i stink at math but theres alot of people really good at it and good at helping on here to

Answer 18

Yeah, I posted it. It's not entirely simple though so people aren't answering it :( Oh well! I'll try my best.

Answer 19

heree send me the link to you question ill send it to @experimentX he is really good and helpful mmaybe he could help

Answer 20

Thanks! I messaged him.

Answer 21

mmks np =) goodluck!

Answer 22

??
i was here since you tagged me

Answer 23

haha i just tagged you so you would see i was hoping you could help xxaloserlikemexx out

Answer 24

And don't be fooled by the username. It's a thing from a TV show. I'm actually quite good at math.

Answer 25

haha ok =)

Answer 26

what's the question??

Answer 27

18. Read the two statements shown below.

If the weather is not cold, Meg will go swimming.
The weather is cold, or Meg will go swimming.

Create truth tables for the logical form of the two statements (not to be submitted). Use the truth tables to determine whether the two statements are logically equivalent. Justify your answer.

theres the link

Answer 29

The only thing I'm having trouble with in geometry are these types of questions.

Answer 30

lol @cbrusoe ... did you follow the link i gave you?? it's exactly same as the link i posted. just replacing p and q by two parts of the single statement!!

Answer 31

This is my work so far:
Let p and q be two statements.
p: The weather is cold.
q: Meg will go swimming.

If the weather is not cold, Meg will go swimming.
This statement is symbolically written as ~p → q.

The weather is cold, or Meg will go swimming.
This statement is symbolically written as p v q.
Now I have to make a truth table for both to see whether they are equivalent or not.

Answer 32

lol why did you tag me on my question? ;p haha and what about the link?

Answer 33

If the weather is not cold, Meg will go swimming. ==== false

Answer 34

oooh i had this same question... hahaha

Answer 35

yeahh he is good at helping with this stuff for sure lol @experimentX do you want me to go get the links u posted for me?

Answer 36

I'm still confused as to why it's false though.

Answer 37

Sorry ... i didn't see not there
If the weather is cold, Meg will go swimming. ==== false
If the weather is NOT cold, Meg will go swimming ==== true
If the weather is cold, Meg will NOT go swimming ==== true
If the weather is NOT cold, Meg will NOT go swimming ==== true

Answer 38

you could have put that in reply to my question instead of the links -___- lol

Answer 39

This is basically my last resort. My teacher isn't calling me back and I need to finish this test. So the statements are not logically equivalent? Or are they? I'm still confused.

Answer 40

this is your truth table of first statement
The weather is cold, or Meg will go swimming === true
The weather is NOT cold, or Meg will go swimming === true
The weather is cold, or Meg will NOT go swimming === true
The weather is NOT cold, or Meg will NOT go swimming === false

Answer 41

they aren't logically equivalent the first one is true the second one uses or in it's statement so the second statement is either or true

Answer 42

did i get that right @experimentX?

Answer 43

Okay, that makes sense. I'm not exactly sure how to do the other one though. I believe since it uses the "or" only one of the parts has to be true for the statement to be true. Am I correct?

Answer 44

If you take
weather is NOT cold => true
Meg will go swimming => true
Then,
The weather is cold, or Meg will go swimming === true
The weather is NOT cold, or Meg will go swimming === true
The weather is cold, or Meg will NOT go swimming === false
The weather is NOT cold, or Meg will NOT go swimming === true

You see ... Meg doesn't five a damn about weather!!

Answer 45

Hehe that made me laugh! So they are not logically equivalent? Because don't the truth tables have to be equal or something? My teacher is horrible at explaining concepts and I'm pretty sure she said that, but not completely.

Answer 46

XD I enjoyed that explanation

Answer 47

OR <--- mathematically means ... if one of them is true ... the whole is true ...
so if Meg goes to swimming or Weather is good .... then it's time for party!!

Answer 48

=) =) =)

Answer 49

I hope you understand ... and next time don't shoot this type of question on me!!

Answer 50

Okay! That makes much more sense. So, in the first statement she /does/ care about the weather and the second she doesn't?

Answer 51

I'm sorry. It was very helpful though, thank you! :)

Answer 52

lol mmks thanks @experimentX =)

Answer 53

okay ... though i did not expect you to read these stuffs in 9th grade!!

Answer 54

I'm actually in 8th grade. I'm taking honors geometry. :)

Answer 55

=p yeahh what grade are u in @experimentX or are u graduated nd all

Answer 56

I am graduate!!

Answer 57

otays cool

Answer 58

seeya
