Can someone help? Anyone?

OpenStudy (anonymous):

These are the five questions.

OpenStudy (anonymous):

I know some of the answer I just need to see if I got any right

OpenStudy (rational):

you need at least "two" points to form an unique line

OpenStudy (rational):

it has multiple options that work

OpenStudy (anonymous):

is 1. A C and D?

OpenStudy (rational):

@heather2292 is on mission to help everyone today ;)

OpenStudy (anonymous):

Those were my answers to 1

OpenStudy (anonymous):

i am haha

OpenStudy (rational):

yes A, C, D work for first question

OpenStudy (anonymous):

I need at least an 80% but 70% percent is good too

OpenStudy (anonymous):

i really dont think its c and d. thats not how you write that. its supposed to have a line above the letters like letter a. it is not supposed to say the word line

OpenStudy (anonymous):

I took this 2 times and there are others without the line :/

OpenStudy (anonymous):

so it can be both? the line above the letters and the word line?

OpenStudy (rational):

yes im more or less sure that q1 has to be A, C, D

OpenStudy (anonymous):

Yes it can be both

OpenStudy (anonymous):

i didnt know that

OpenStudy (rational):

saying "line KD" is same as saying \(\overleftrightarrow{KD}\)

OpenStudy (rational):

just a different (unusual) notation..

OpenStudy (anonymous):

okay thank you. learn something new every day haha

OpenStudy (anonymous):

Is 3 A,B,C or A,C

OpenStudy (anonymous):

I chose A,C

OpenStudy (rational):

wait what did you get for q2 ?

OpenStudy (anonymous):

plane is the label of the lines (or how ever you say that lol) so it would be R because R is in the corner and the label

OpenStudy (anonymous):

B and C

OpenStudy (rational):

Yes. fo q2, options B and C look good !

OpenStudy (anonymous):

I know R is a plane but I need one with lines like JAU or something I was just wondering If A and C are correct so I don't know about 3

OpenStudy (rational):

For q3, you need at least 3 "noncollinear" points to name a plane, so you can eliminate option A straight away

OpenStudy (anonymous):

Oh okay So its B and C again?

OpenStudy (anonymous):

i think b and c

OpenStudy (rational):

Yep! option D is also eliminated because all the 3 points in that option fall on same line which is no good for a plane

OpenStudy (anonymous):

Oh okay I didn't choose that one because that wasn't it :D

OpenStudy (rational):

lol what about q4

OpenStudy (anonymous):

I chose D for 4

OpenStudy (rational):

nope, one letter is sufficient for a point

OpenStudy (anonymous):

a point is only one letter

OpenStudy (anonymous):

Oh okay is it B?

OpenStudy (rational):

do you mean option B ?

OpenStudy (anonymous):

Yes :D

OpenStudy (anonymous):

correct

OpenStudy (rational):

Yes!

OpenStudy (anonymous):

yayyyy

OpenStudy (anonymous):

\(^o^)/

OpenStudy (anonymous):

q5

OpenStudy (anonymous):

what do you think the answer is

OpenStudy (anonymous):

Is question 5 A and B?

OpenStudy (anonymous):

I chose A and B for 5

OpenStudy (rational):

option B has only one point, so it cannot represent a line.

OpenStudy (anonymous):

Oh okay that's were I failed the first time ^o^

OpenStudy (anonymous):

soooo just a

OpenStudy (rational):

there is another option that works...

OpenStudy (anonymous):

whats that?

OpenStudy (rational):

line g

OpenStudy (anonymous):

how

OpenStudy (anonymous):

Line G ?

OpenStudy (rational):

we use small case letters to represent lines usually

OpenStudy (rational):

both options A and C represent lines

OpenStudy (anonymous):

ohhh g looks like its chillin in outerspace

OpenStudy (anonymous):

Oh okay lol

OpenStudy (anonymous):

I can only medal one person but I'll fan the both of you Thanks for the help I'll let you know if I got a good score ^o^

OpenStudy (anonymous):

OpenStudy (rational):

OpenStudy (anonymous):

I got a 100% Thanks guys ^o^

OpenStudy (anonymous):

omg yayyyy!!!

good job
