00:00

Thank you We sneak and here's your daily scribble brought

00:05

to you by math crimes If you're ever caught stealing

00:08

a number your case will be handled by the subtraction

00:10

division All right you're an undercover cop and you're trying

00:13

to infiltrate the biggest baddest math gang in town You

00:16

need to rise up in the ranks and get close

00:17

to the leader to see if the rumors of math

00:19

crimes or true you've finally got a meeting with the

00:21

gang's leader a triangle expert and you need to prove

00:25

yourself to her She just asked you to construct a

00:27

triangle whose angles are eighty degrees fifty four degrees and

00:30

fifty six degrees And yeah she's testing you to see

00:33

if you can hang with the big dogs Can you

00:35

make a triangle out of those three angles Why or

00:38

why not Well you might be tempted to whip a

00:40

protractor and start drawing this thing right away But hold

00:43

up when were given three different angles and asked to

00:46

make a triangle out of them We should always test

00:48

the angles out first We can't just make trying a

00:51

lot of any old trio of angles we need to

00:53

Make sure this is even physically possible right How do

00:56

we do that Well there's One specific rule about triangles

00:59

All three angles need tto add up to one hundred

01:01

eighty degrees period where the triangle won't physically possibly be

01:06

able to connect your the most respected math cop on

01:08

the force So how would you pass her test Well

01:11

add up all three angles she gave you got eighty

01:14

fifty four and fifty six Well eighty plus fifty for

01:18

we get one hundred thirty four plus fifty six that

01:20

gives us yeah one hundred ninety So that's ten degrees

01:24

Too many in this triangle expert is trying to trip

01:26

you up You just calmly say to her that triangle

01:29

is impossible They smile You passed your test You probably 00:01:33.097 --> [endTime] don't have to act so smug about
