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
