Difference between horizontal and perpendicular?
 

I'm a little confused about the difference of the two words. In Wiki perpendicular sounds like horizontal to me so I hope someone here can clear me up a little.

thanks!

--------------------------- << this is a horizontal line
--------------------------- << this horizontal line is parallel to the first line.

Uh, Zerg, you mean parallel.

Actually, those two lines are parallel to each other. Perpendicular means you have a 90 degree angle between the two lines.

Ergo: _|_

I posted too fast. Changed :p

Elrasiel:

x <---these lines are perpendicular (for the most part)
+ <---these lines are also perpendicular

x <---has no horizontal lines
+ <---has a horizontal line

Perpendicular is a term used to define the relationship between two lines, while horizontal is a term used to define the relationship of a line (or plane) to the entire world.

To remember 'horizontal' I always think about the 'horizon'... its side to side as opposed to up and down.

As for perpendicular, its just two lines interesecting each other... I believe it has to be at a 90 degree angle. Perpendicular, you need two lines. Horizontal is just one.

i believe the earlier pictures cleared it all up.

Thanks y'all!

Cleared my pipes all up.

Wow.. is it just me or is GFF's level of intelligence dropping at an incredibly surprising rate?

I think it's the latter that holds true, Vemp.
