Brilliant! That was the best proof I've seen for Thales' Theorem. Good clear presentation!

When I was exposed to mathematics in my formative years, many decades ago, I had difficulty, even though, I otherwise had a technical mind. A condition, unbeknownst or misunderstood by the learning community, caused my mind to reject mainline, more direct paths of learning in favor of indirect, often more circuitous paths, otherwise known as dyslexia. In Jr High School the math department used a method that split the teaching session into two parts: 20 minutes of instruction and 20 minutes of student demonstration at the blackboard. For me that was absolute traumatic humiliation. I aced my exams and was placed into advanced class curriculum, but when forced to perform in front of an audience, using my alternative dyslexic logic, my mind froze solid and the students were as unkind as you might imagine. The teachers suspected that I was somehow cheating on my exams, before thinking I might have had a severe performance anxiety. Math became a nightmare for me and any hope of an engineer career was dashed completely. The same dynamic played out when I tried to learn music which impossible because dyslexics scans texts and scores erratically. This tutorial bypassed my dyslexic difficulties. Thank you

I love you. Please keep doing this. My 6 year old child loves them too. I failed math growing up, yet I'm a respected programmer. Funny how that works, Your videos helps me understand fundamentals. Thank you.

So simple! But I wouldn't have seen it in 1,000,000 years.

even after you've gone, you're still around to teach us something new, just when I was looking for this, how comforting it was to find a video from you that explains it best than others.

The last sentence is very inspiring

Amazing! I had to prove this theorem for a math class and I was unsure on where to begin. Only wish I would have found this earlier. Great video!

A channel I strongly recommend for fascinating mathematics is Numberphile!

Love your videos! You make the ideas come alive in a beautiful way. Thank you.

Thank you, Sir, for posting these precious videos.

Thanks, took me back to the time I first learned Geometry and came to love it.

Thank you this was very helpful and easy to follow keep up the good work. Thank you!

This is profoundly interesting.

Simple, to the point n clear explanation. As is Thales was a wizard who made life simple for mankind.

Thanks for the video! Very informative!

Thank you so much Sir, for this precious Video.... 🙏 🙏

Thanks! It was really helpful!

wow, amazing! thank you for this great and clear content!

why is not this called a law rather than theorem? Isn't it valid in every circle?

i knew this this in school but never knew it is thale, thank u

Suck a great video that gets to the point. Thank you!

excellent video. Thank you very much.

Can you believe a person from 600 BC figured this out. Thinking about that Blows. My. Mind.

explained well, thanks.

Good work!Big up Mr

In my humble mind I'm trying to understands how the Egyptian managed to build the pyramids and how much they did know about geometry. Thank you, I know a bit more about the "Intercept Theorem"

you saved my math test. legend!

beautiful theorem. and very easy to proof

This helped me SOOOO much

Failed math 3 times at a major University, but I get you (U). Thank you, Hilaroad!

Thank you for this!

Very interesting, thanks

magnific explanation.

In order, can someone tell me who discovered those equations near the end of the video?

THANK YOU 🙌

Very nice video

Is this proof of theorem and figure is right for attempting in examination

Brilliant

great thank u

This theorem blows my mind every time I see it. Thales was a genious. Can somebody provide a proof that the two anlgles of an isosceles are equal (if there is such a thing)? I know is self evident, but not so mathematically.

I gotta like and subscribe to this one.

Its like magic

Perfect

Is it ok to say this: lets add another point F as [DF] is another diameter. Then [AB] and [DF] meet in their middle : so ADBF is a parallelogram. And as AB=DF, it's a rectangle. So the angles are 90°.

AmAAAziiiing

👍🏻👍🏻👍🏻

super

wow, i did the same thing thales theory did, and it was the truth because that angle D. no matter what point you put it in a diameter, it will always be 90 degree, which always equals others by 180 degrees.

Cool

جميل ومفيد

how do u prove the sum of interior angles of triangle is always 180

Gonna listen to some ACDC now. Some B-sides.

My Sir thought me this theorem in my 8th grade but he never told me that it is known as THALE'S theorem

or you can use a protractor

6:16 Thales himself stood on the shoulders of the Egyptians.

the dislikes are from people that didn't understand :>

One question tho, I agree you simply followed the proof of Thales' Theorem, but when you said that the sum of the interior angles of a triangle will always be 180 degree why was there no proof? (you did not show us the step of measuring the interior's added all together to make a 180 degree), it was only the variables you presented as X and Y.

Thales : i wish i were presented in this Century 😭🐽

It is wrong you can't write X + X + Y + Y equal to 180 by saying that sum of interior angle of a triangle is equal to 180 degree

Isaac Newton was an Occultist who just so happened to learn mathematics along the way.

well youve certainly proven im not the brightest :D

Hmm... So Thales made 2 theorems? Ok. Maybe more, then.

couldn't he just... take a suad ruler?

kzfaq.info/get/bejne/jJuahKxpu5nSo4E.html#t=326 x+x+y+y and 2x+2y and 2(x+y) they are all just the same thing. so basically that only proves one thing.

Weird that this has nothing to do with what my teacher explained..

who's here from HEHE PRODUCTIONS

Read Euclid's elements with the real wish to understand his view of the depth of understanding of the things we see or see before practising it...moral examplified by Ancient Greeks...we are not sheep or r we made sheep by shit education system?...

Again, a lucid explanation...

who where his teachers?? bullshit he invented this, it was already known long ago in Egypt.

Is this proof right are you sure this proof is right

I'm sorry, but I just don't believe it.

Brilliant
