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

00:00

Thank you We sneak in then here's your daily scribble

00:06

brought to you by stretching because there's nothing worse than

00:09

pulling a hammy If two different lines stretch out infinitely

00:13

but never touch what's the relationship Well they're certainly not

00:17

dating on let's Think about this in a couple different

00:20

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
