math question :) please help?

Question

explain why two lines that are perpendicular to the same line are or are not always parrallel to each other.


thankyouu

Answer 1

Liz's answer is right. Two lines may be perpendicular to the same line but not parallel to each other if you are in 3-space and not a plane. Lines like that are called "skew".

Answer 2

3 dimentions.
If your main line is going up <-->down
you can have an east<--> west and a north<--> south that are both perpendicular.

****
So yeah.
In space they are NOT always parrallel, but on a plain they ARE
ignoring the pyramid in this image:

you can see that the blue and the red lines are both perpendicular to the green line and also perpendicular to eachother. you could crate a circle of lines perpendicular to the green line, and none would be parallel to each other.

Answer 3

I'm pretty sure that when there are 2 lines perpendicular to one line the 2 other lines are parallel. We did this a few weeks ago in my geometry class. soo there would be 2 lines like this

and then a line like this

except its a line
that one line would be perpendicular to the 2 other lines.
the other 2 lines ARE parallel, they can't not be, =]

Answer 4

gurl ur question made me think really hard.....

seriously, it should always be parrallel, im not sure.... coz everytime i think of it, its always parallel

geez this is really hard.... where did u get it?

ooo yea the one above me get it.... its 3d like the vertex of a cube...
