No hablo ingles pero entendi todo a la perfeccion. El lenguaje matematico es universal..
Es verdad
I guess it's something like "no English is needed here. The Maths language is universal". Am I right?
The translation is: “I don’t speak English, but I understood everything perfectly. The language of mathematics is universal.”
Yo entiendo inglés pero no entendí una mierda.
Naj es broma, sí entendí.
@@kasra72389 you are right
What an elegantly simple derivation. Gotta wonder why this was never explained in grade school.
This proof is there in class 9 math textbook
@@rudragajjar454 cbse?
@@VANTABL4CK Yeah chapter 6 lines and angles
this could be taking notes but thank you so much I really need help with math 😃😉
Non Euclidean geometries:
I'm going to end this mans whole career.
😭😭😭😭 I’ve researched non Euclidean geometry on my own and I’m not happy to do it in college haha
I really loved your explanation of Binomial theorem!
Wow , this is an awesome way of analyzing a concept.
This is far better than the environment in which we were taught , thanks a lot .
Don't memorize stood by it's name, we are really learning in a way we don't have memorize
Watching all of your videos from oldest to newest. This will take a few days; but should give me a very strong understanding of many areas of study.
I'd prefer reasoning this way: i.e. driving around the corners & returning to where you came from.
*At each point you deviate from going straight forward by 180-(internal angle) degrees.
*In total, you go round once and arive at the same direction of walking/driving i.e. rotate 360 degrees.
So combined: 360=3*180-a-b-c where a,b,c are the sizes of the internal angles from the different corners. Add a+b+c-360 to the left and right side of this equation and you get:
a+b+c=180
Q.e.d.
I didn't even thought that any body can look at the angles of triangle from such an angle. It helped me a lot to do my project work.
Thankyou team @Dont memorise for helping us out through your videos
Finally found something useful
Thanks a lot😊
Keep making more of such videos.
Thank you! Best concise explanation online.
Very nice, concise, clear proof.
Thank you. :)
Nicely done. Very clear and easy to follow.
Thanks video made me learn alot about angles!
Wow! This is truly an awesome demonstration.Far and away the best I've come across in a long time. Do you teach other math topics such as pre-calculus and calculus? Thanks.
Hey Daniel, we haven't worked on those topics yet, but we will for sure! Soon :)
I didn't under stand
@@arshadali5109 the explanation is amazing. Just watch and also try it out on paper. U will surely understand it.
@@InfinityLearn_NEET hi
@@InfinityLearn_NEET What does remaining angle means?
Thank you very much...clear, concise, and complete, short of explaining why it might be the most important topic in Geometry. I actually did quite well in Geometry in High School but I'm afraid that was many years ago. Although I could remember that the sum of the angles of a triangle equaled 180 degrees, I could not for the life of me remember why, which is always the most important aspect of learning anything. That five year old may be able to answer correctly for more topics immediate in their life, but I really don't think they're smarter than me... well, not all of them anyway.
Thank you very much for the appreciation and for watching.

Superb explanation. Who are watching this in 2019 .
Clever👍thank you
Awesome learning channel..
Thank you for helping me!💗
Great! Simple! Worthy! :)
Nicely done! Thanks for posting.
Is this the new minecraft enchantment table accent?
XD
Lol
Lol😹😹😹😹
I wish i could get this kind of education before... but no problem i am here now and enjoying these leactures. Thank you sooo much.
THANK-YOU SO MUCH YOU SAVED MY LIFE
+jarin hawlader , awesome :)
Thanks to make it easy.
Simple and beautiful. Lovely voice also.
Better than any other math video,well explained,I was quite afraid for my exam as this question was for 4 marks...Thank you for sharing such a great video
Awesome explanation. Thanks alot!
I have never seen such a good, thorough explanation of why the interior angles always equal 180 degrees. This just goes to show the failures of the U.S. educational system, as none of my schools ever presented this. They are always about rote memorization, not the underlying theory. I had to watch a couple times, but then it clicked and the light bulb came on.
Thank you SO much for this!
I think this Channel is Indian as I am too
Thank you
Thanks for your help 😎
You are most welcome, Hemanth!
We are happy to help😊
The number 180 is arbitrary. This number has been chosen because it can be divided by many numbers, so the results (partial angles, smaller angles) would be integers. That's why the angel of a straight line is 180. And as a result of this, the sum of the angles of a triangle is 180.
It can be also reversed: We can decide that the sum of the three angles is 180, then the angel of a straight line would be also 180. This is true only in Euclidic Geometry (Plain Geometry).
Water boil at 100 degrees. why? The answer is the same. It is also an arbitrary number just for convenience.
zohar99100 Not quite. It is not that 180° was chosen arbitrarily. Not at all. Rather, it is derived from the definition of the circle as being 360°, with the latter being arbitrary. However, this difference is important, because there is much more justification to start with 360° than to start with almost any other number.
This video cleared my doubts.Thank you😊
Very very very very very very very very 10000000000000000000000000 times very nice explaination it was mindblowing
Great voice with a spectacular way of teaching. Understood the concept under 2 min. Thanks alot .
Thanks I was confused but now I get it now
Thank you very much
Can you teach 11th Mathametics like calculus and differentiation
This is awesome!
Really amazing channel small things are really neglected in education system but u people are even explaining from basics really great please do lot of videos
Really interesting!
very perfect thank god its very useful for my math exam 😃😃😃😃

This thorem is very simple in exam time
Thanks
Im getting 30s on my tests now that I started trying to find out the sum of the percise degree in all triangle of an angle. Need alot of help I had it all down and more and now just have a serious downfall in a platow series. My mind says strike on the exact moment it sees that I will be weak because of it. All I need is a tutor I have never had. Not telling me how wouldn't be the answer.
wow! nice video and content!! surely worth a thumbs-up! :)
Thank you very much for the love and support.
Happy Learning :)
thanks
Clear as water... Great explanation

Thank you! this made it so simple.
Hi
One of my childhood mystery get cleared today
Thanks
Hi
Nicely explained.... thank you very much
A proof I learnt in high school was cut out a paper triangle and fold it so one corner is resting on the opposite side. You'll find that the other two corners can be folded in to meet that first corner so that all three corners together form the sum of the angles on a straight line, which of course is 180 degrees.
Thanks Very much I am now prepared for test
I had a project of derivations.
whatever derivation I wanted ur video is there and for all derivations, I watched ur video
thanks a lot
Wow!...that's was great....you are my another new teacher from now!
Nice! This explanation is just Amazing 😆
I understood everything 😁
Thak uhh soo much :)
Excellent videos...THANKSSSSS....
वाह, मज़ा आ गया, धन्यवाद
Thank you, you’ve done a great work
thanks for your help.....
You're welcome Zyle :)
Thx it is nice 👏😊
Great video! Just curious, is there another way to prove the triangle sum theorem?
Absolutely 👌👌👌 Great video.This video cleared my doubt .keep it up.
And I love these 2 words
"Don't Memorise"
So what degrees does each letter represent? If the triangle is off set the degrees of each angle will be different but will add up to 180* but how do I work that out???
Thankyou so much for your explanation
Thanks 🙏🏻
Such a great explaination
Would be complete if you mentioned synthetic geometry where postulates and constructions are the main tools to 'prove' anything geometric. Nice video btw!
Nice video. Really helpful
I knew it but not sure about it
Thanks
You did proof this very well. I subscribed after this video.
