2. Lines line L M and line N P on the same plane (coplanar) but do not intersect.

OpenStudy (anonymous):

so ?

OpenStudy (anonymous):

how do i draw and label these lines?

OpenStudy (fibonaccichick666):

if they don't intersect, then the lines are what?

OpenStudy (fibonaccichick666):

what are they called?

OpenStudy (anonymous):

parallel lines

OpenStudy (fibonaccichick666):

right so what do we know about parallel lines?

OpenStudy (fibonaccichick666):

other than they do not intersect

OpenStudy (anonymous):

they dont touch, but how do i label these lines.

OpenStudy (anonymous):

they dont intersect

OpenStudy (fibonaccichick666):

do you know anything about their slopes?

OpenStudy (anonymous):

no i just need to draw them and label them, this was all the info i got 2. Lines line L M and line N P on the same plane (coplanar) but do not intersect.

OpenStudy (fibonaccichick666):

or slopes of parallel lines in general I mean

OpenStudy (fibonaccichick666):

sorry it was vague

OpenStudy (anonymous):

no worries : )

OpenStudy (fibonaccichick666):

so the slopes of parallel lines are _____?

OpenStudy (anonymous):

what do you mean, i wasn't given a slope for this question.

OpenStudy (fibonaccichick666):

in general (so you can label the lines), let's say the slope of this line is A and this other line is parallel to it what is that line's slope?

OpenStudy (anonymous):

A, Any line parallel to this line has the SAME SLOPE

OpenStudy (anonymous):

I will show you what i have drawn, please tell me if it looks correct. one sec

OpenStudy (anonymous):

here it is

OpenStudy (anonymous):

1. I need to draw and label two planes that do not intersect... (I am unaware how to do this) 2. Lines line L M and line N P on the same plane (coplanar) but do not intersect. 3.Points X and Y lie on line A B.

OpenStudy (anonymous):

please help : (

OpenStudy (fibonaccichick666):

yea thats why you need to know about the slopes.

OpenStudy (fibonaccichick666):

and yes that is correct\ A

OpenStudy (fibonaccichick666):

ok so what is a plane?

OpenStudy (anonymous):

so are my answers correct ? I mean my attachment

OpenStudy (fibonaccichick666):

not quite uhm so if you have an x-y axis that is a plane. now you want two lines on that plane but they need to be parallel

OpenStudy (anonymous):

you mean for question # 3

OpenStudy (fibonaccichick666):

NO THE ENTIRE PROBLEM

OpenStudy (fibonaccichick666):

oops caps lock was on

OpenStudy (anonymous):

ok

OpenStudy (fibonaccichick666):

uhm let me give you an example 1)two lines are coplanar 2)they intersect 3) they are perpendicular

OpenStudy (fibonaccichick666):

|dw:1367556122177:dw|

OpenStudy (fibonaccichick666):

understand?

OpenStudy (anonymous):

no

OpenStudy (fibonaccichick666):

ok what part of the pic do you not understand? (so I know where I need to explain)
