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

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

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
