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

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
