Geometry - Angles of Polygons

In a summer school edition of Yay Math, we wade into understanding polygons, and name a bunch of them from 3 sides up to 12.
Then, we find the number of triangles "hiding" inside every polygon. That leads us to uncover the formula for the sum of all interior angles, which is 180(n-2)... DON'T WORRY, we'll explain that!
Then, we define "regular" as a polygon having all equal sides, and wrap up by learning about the sum of all EXTERIOR angles of any polygon. That sum of all exterior angles is always 360 degrees.
Yes, we covered a lot of ground, credit to the students, joining me for summer school. YAY MATH!
Learning should always be fun and connective. Please visit www.yaymath.org for:

• free quizzes
• free worksheets
• debut book on how to connect with and inspire students
• all-in-one math courses that teachers and parents can use, backed by Yay Math energy

hell of a teacher i wish i had you

[@firstlast6592]

Same. My maths teacher always shouts limps and smells of smoke/ciggs.

[@SushilSingh-kj7gm]

same

[@richjoybello6483]

Oh good thing our math teachers is Nice and she explains the subjects or lessons pretty well sometimes we do nothing and Im from Philippines but we learns this things too and we even recite this in front of our classmates and 11 is - Undecagon 🙂

[@maxbuhler4423]

What’s 3 sides called Kid: uhhhhh Teacher: triangle Kid: dang I was close

[@jonathangomez3079]

Teacher: "6 - hexagon... 7 - ...." Kid: "mex-o-gon..." This is when I realized it's real students he's teaching haha good one.

[@jodikaitlyn1560]

This helps me out so much. I love your videos and they always help me with studying before my tests. Thanks for doing this you're a great teacher and I hope you keep up the good work. :)

[@gracegotzinger3513]

too many people talking in the backround... you fix that!!!!!!!!!!!!!!!

[@MrHappiness]

It so cool hearing audience voices,it is creating cool atmosphere

[@whatervr]

this helped me so much, im doing an access course into uni, and ur videos are very fun and easy to learn.

[@sincerelyaidan]

[@arirara7301]

Amaaaaaaazing!!!!! I wish you were my Maths teacher!!! :P

[@lesleys111]

been watching your videos a long time ... just joined your mailing list. As a prospective teacher, you are a great mentor. Really like your style.

omg thank you so much, you just helped me with my quiz tomorrow! until i saw this vid i didn't understand polygons. Now i do :D

[@alicegalnawan5434]

Teacher: How much sides does a triangle have? Kid:3! Other kid:4! Me: Yo WHAT THE FREAK?

[@ivar3770]

lol

[@catherineferreira4518]

alice galnawan they prob being kids or not paying attention .Its funny 😂

This teaching connect the students to the subject matter. Though i don't have students interaction in my video but i must say that ve learn a lot from you especially teaching through patience

[@yuvrajthakur569]

thank you for this amazing lesson

[@rogermorales9692]

i just realized i watched a 20 min video when it felt like 2 min, that makes this a good video

[@jessicaconrrad524]

LOVE what you are doing! My 3rd grade students earn extra credit points for previewing your videos before my lesson! Thank you :)

[@darlinglassila]

coolest math teacher,,, koddos,,💙💙

[@zahranoor7984]

you're a LEGEND

[@thefigtreeguy]

I need to make two corrections here regarding the naming of three and four sided shapes: kzbin.info/www/bejne/rp3WhH9tg7CEb7c Only a Greek can see the major difference in the naming theses shapes. Also, gon is the "knee" in ancient Greek. Since ancient Greeks had not invented the measure of angles, but had realized that angles do change similar to a "knee".

[@Skeltonz]

i dont know if you'll reply but what if you use opposite sides to create the parallelogram but you have to find the variable but its in fraction form example b/2 and i have to solve for b how would i solve it? i didn't understand it all the way but your a good teacher this is the only one i didn't understand

[@hinarehman6231]

If all sides of hexagon will not equal than still all exterior angles remains 60⁰?

[@danam7929]

I love his explanation and his class is incredible they did some noise but nevermind

[@internationalballerofficial]

you are a great and very friendly teacher

[@kimcuchoang422]

it is really good , thank you so much .

[@unlimitedgames9611]

Where do you work so I know where to go for school

[@MrHappiness]

Amazing!!Also cool atmosphere at the lesson👍Thank you very much!You are wonderful teacher!

[@grizzledwarveteran2321]

what would be the exterior angles of a 360-a gon and beyond? Less than 1

[@MelodyH411]

How did you find the inside angles again?

[@abey4827]

MelodyH411 (n-2) *180 / n

[@samuelbriandacayana5467]

180-Exterior angle= interior angle

[@jundezkmaravillas3966]

N- sides i= interior angle = 180° (n-2) = x x÷n= i

[@wajihatariq2426]

OhMyGod I love this guy.

[@sartajs2638]

I liked the way of explaining

thank you

[@sandragonzalez-xf8fs]

how did he get the interior (135)

[@Nemo-xy4nk]

180-45=135

[@whatnoitsbryan1015]

that was so amazibg ._.

[@rickyg3742]

had to go on here since my actual teacher was no help

[@Thehiddenwarrior123]

this is the best

[@hannahwhitman1688]

How did they get 135

[@lhanso20]

The 90 degree angle plus the 45

[@natedavis1277]

hannah whitman u have to subtract it from 180

[@bilalmuhammad1547]

amazing

[@arushaansar1296]

I so wish u were my geometry teacher 👨‍🏫
