I've only recently looked at this stuff myself. When I was in college ( a long time ago) we never did this. From what you have stated I'm pretty sure that it's a ray.

- anonymous

anything else?

- welshfella

oh - can be more than one...

- anonymous

yeah

- welshfella

- it also says in the link that a ray is a portion of a line.

- anonymous

so line segment? I don't want to get this wrong...

- welshfella

no its not a line segment A line segment has 2 endpoints

- welshfella

https://www.mathsisfun.com/definitions/line-segment.htm

- anonymous

so its just ray

- welshfella

I'm wondering if its also a line..

- welshfella

No - because a line extends indefinitely in both directions
I would say its a ray only.

- anonymous

there are a few more of that kind can i ask them

- welshfella

@ganeshie8

- welshfella

I'd prefer to check with ganeshie if hes available

- anonymous

ah okay

- welshfella

oh pgpilot is here
can you confirm what I have said? @pgpilot

triciaal?

- triciaal

huh think a ray

- anonymous

can i ask a few more? Sorry im in middle school and i really need help

- anonymous

but i understand what you are saying..

- welshfella

- it used to be just a line!!!

- welshfella

I notice that US and UK algebra are very similar but there are quite a few differences with geometry

- anonymous

so its ray?

- welshfella

yes

- anonymous

A straight arrangement of points extending without end in opposite directions
ray, line, line segment, point? (could be multiple)

- welshfella

a ray only

- anonymous

the next one is ray too?/???

- welshfella

oh sorry I was referring to the first question

- triciaal

look at my drawing now I think it is correct line no end

- welshfella

check triciaal's post what do you think?

- anonymous

is this one line?

- welshfella

looks good to me

- anonymous

k 2 more

- anonymous

has no dimension,
is on of the undefined terms of geometry
line, line segment, point, ray? (again, could be multiple)

- triciaal

point

- triciaal

wait

- anonymous

ya?

- triciaal

In geometry some words such as point, line and plane are undefined terns.

- anonymous

lol so what is your "point" XDXDX?

- triciaal

point no dimensions represented by a dot
line extends in one dimension represented by a straight line with 2 arrowheads to indicate the line extends without end in 2 directions.
a plane extends in 2 dimensions. represented by a shape that looks like a table top or wall. extends without ends.
collinear points points on the same line
coplanar points lie on the same plane.

- anonymous

so it would be point right, since its undefined then its a point????

- triciaal

the ray AB consists of the initial point A and all points on AB that lie on the same side of A as point B

- anonymous

so it is point right???????? its yes or no

- triciaal

just typed from the geometry textbook.

- anonymous

so it is point.

- triciaal

thought you were just messing with me yes point no dimensions spot

- anonymous

k one more i have a feeling it is line segment
part of a line that consists of two points called endpoints and all of the points between those endpoints

- triciaal

I said wait because I was about to type from the page. seems like you might be using the same textbook

- triciaal

yes correct

- anonymous

k thats is thanks

- triciaal

do you happen to be in California?

- anonymous

uuuuuummmm no in florida XDXDXDXDXDXD

- triciaal

ok see you soon

- anonymous

a ray radiates... outwards from a point, in a particular direction.
the negative or opposite of a ray, radiates outwards from a point in the opposite direction.
