Daily Scribble: Lines in Math

We love scribbling as much as the next person, so we decided to scribble together about lines! Enjoy!

ways What happens when two lines air stretching away from

00:23

each other increasing the distance between them That might seem

00:26

like it could work But remember aline is always infinite

00:29

in both directions That means that if our two lines

00:32

were stretching away from each other at the end they'd

00:34

actually be getting closer together at the other end Got

00:38

it What about two lines that are running in opposite

00:40

directions Well that depends on what we mean by opposite

00:44

They can't be running in truly opposite direction since they're

00:47

both infinite lines Without any end points they each already

00:50

go in both directions We could have two opposite reyes

00:53

but not to opposite lines What if we tried to

00:56

draw one vertical line in one horizontal lines Well would

01:00

they intersect on a plane Well try drawing Vertical line

01:03

That takes up a whole sheet of paper Top to

01:05

bottom and then tried running of a horizontal line on

01:07

the same paper that doesn't hit the critical one And

01:09

it's impossible right there always gonna intersect well the only

01:13

way this woodwork is if the two lines never got

01:15

any closer or farther away from each other That means

01:19

they've got to be parallel because parallel lines are the

01:22

only type of lines that never touch each other They'll

01:25

look like an equal sign but stretched out to infinity

01:27

in both directions Yeah it's like two cars going the

01:30

same speed on a highway right next to each other

01:32

in two different lanes Parallel lines are perfect drivers They

01:36

never ever crashed Or have it reported it to the

01:40

insurance companies and we'd know about it eh Come on
