Transcript

00:00

Thank you We sneak in and here's your smoke du

00:05

jour brought to you by a guilty triangle It's really

00:09

wishing it hadn't stood up so fast All right a

00:12

right triangle with sides labeled l lemon and has shown

00:15

below if s l stands for the slope of l

00:19

and s M stands for the slope of m and

00:22

s and stands for the slope of end in which

00:25

of the following statements must be true and hear the

00:28

potential answers Seven his life Okay so what's this question

00:35

asking Well we're given a graph featuring a triangle that

00:38

looks badly in need of its morning cup of coffee

00:40

way And we need to figure out what would happen

00:44

if we multiplied the slopes of the three sides of

00:46

the triangle together They're no given numbers here Missed a

00:52

few letters So what gives Well let's look at the

00:55

other information that we are giving problems Says this is

00:58

a right triangle And yet there's a little right triangle

01:02

symbols So we know the two legs of the triangle

01:05

side in inside em are perpendicular ninety degrees member Okay

01:10

so what do we know about perpendicular lines Slope wise

01:14

Well hopefully remember that the slopes of the perpendicular lines

01:17

are always negative Reciprocal sze in other words multiply the

01:22

slopes of any two perpendicular lines and you get negative

01:26

one like if the slopes or three and negative a

01:30

third toe All three terms negative Third is negative one

01:33

and it'll be the same with any too negative reciprocal

01:36

ls he decide to plug in there lose us with

01:38

just negative one time The last side side l were

01:42

looking over The answer choices It makes sense that sea

01:45

would work because negative onetime side l will always equal

01:49

negative side L so yeah we've got her answer and

01:52

our triangle friend has finally got his coffee All is 00:01:54.633 --> [endTime] right in the world
