Olympiad Geometry 奥赛几何
เข้าร่วมเมื่อ 1 มี.ค. 2024
我会在这个频道系统讲解奥林匹克竞赛几何的内容。会按照各个定理系统，各方法论，历年真题多角度解析的方式品读奥赛几何难题。不同于竞赛书籍的解法呈现，在视频中我会重点讲解解题的思考过程，更多关注如何思考和研究平面几何而非追求解题。我会用中英文讲解题目以满足不同受众的需求。大家也可以把想要讨论的题目发至我的邮箱：planery.geometry@gmail.com
Hello everyone, welcome to my youtube channel Olympaid Geometry. In this channel, we will talk about the plane geometry, solid geometry and analytic geometry in math olympiad competition. We will start from the plane geometry and mainly focus on it. We will learn most popularly used theorems and methodologies in solving geometry problems, then we will look at math competition problems in each year. The videos will be made in Chinese and English version.
Also, welcome to send me the plane geometry problems if you want me to discuss about it. My email address is: planery.geometry@gmail.com
I am looking forward to have this fun and exciting journey with you. Feel free to reach out and let me know your thoughts. Thank you.

hi. How could I get those past paper question?
@@Louis-ek5ru I don’t know. Because I collected them 20 years ago from books and internet
Amazing
long years ago i was called it ''ince's chord theorem....because of my surname ince....great lecturing...you are amazing
wonderful...thank you so much
You channel is so underrated Thank you so much for your lessons on olympiad geometry
Good job, you can show on geogebra
yes, I do use it for writing books. I am considering to move to iPad instead of paper. There are pros and cons.
Hi friend, where you from?
@@Cooososoo I’m from China
@OlympiadGeometry-2024 ohh wow I'm from India, nice now I have a friend from China
from Morocco thank you you are genious you present only hard problems....it seem to me you inverted Q and R???..please be more explicit i could not follow
Yes, I made a mistake in problem set. The Q and R should be inverted based on figure, but it won’t change the conclusion
amazing
from Morocco...thank you very much...you solve very very hard problems...you are genious.despite some point did not be clear for me...if please be more explicit and detailled....but if you can type by typer not by hand or write by hand with clear writing the problem at the front of your video...at its thumbnail...now i had your video posed and i COULDNOT read easily more of the data of the problem
this is great!! please make more if you can !!! thank you :)
@@hokagedattebayo7623 thank you for your support!
came here through aops BTW nice video , I suggest you to add more complex and advanced geo concepts also like projective geo,DDIT,inversions, mappings,poncelet points etc ................. :)) Good Luck !
Thanks! All of these are on my plan actually. I want to go over the most widely used theorems and methods first, then introduce the advanced topics
Please do post more videos in English…these help me out a lot.😊
你在後面使用了多次張角定理，但是你如何證明他們的頂角都是對應相等的？謝謝
顶角的对应相等是由对顶角保证的，相当于把筝形沿着对角线对折。也可以想象成入射光和反射光
🇲🇦❤️ good luck brother
看了三讲👍
Excellent proof.
題目二證明三角形BEC和三角形DEA相似是否可以直接證明？因為AD/AE=BC/EC本來就是兩三角形的邊之比，再加上兩個都是等腰三角形且角EAD=角ECB是否可以直接證明完成。
是的，我给出的是我当时所想，不一定是最简洁方法
Olympiad Geometry 奥赛几何, Subscribed because your videos are so much fun!
这种勾史还是放在B站吧，别发到这丢人了
استمرار ❤😂
I cant speak japanese but still understand the proof. This just shows that math has it's own language!!
