Angle in a Semicircle (1 of 6: Standard proof)

[ghousepasha]

I am starting my career as a math teacher, and i watch your videos just to observe how you are teaching a concept. Thank you sir please upload beacuse there is shortage of good math teachers

[marjanfatima]

Thank you so much for these videos!
Your lessons are the main reason that I fell in love with Mathematics!

[AdityaPatel-kxpk]

I go to the school that Mr Woo teaches at and he is a really good teacher! I watch your videos in class and I understand the things so much better. Thanks so much!

One of my favourite mathematics teachers

Thank you for helping my edu!! My former libarian ( like I mean she is still one just I left the school she worked at ) she gave the recommendation and I am alr addicted. So once again, thank you for impressing us with the opportunities u give us

Love the innovation on the circle... So cool Eddie... Thank You...

We can also use "angle subtended at the center is the double the angle subtented by an arc at any remaining part of the circle" theorem
The angle subtented at the center will be 180° in this case, so the other angle will be 90°

ChatGPT told me to go to your channel! Amazing to see an AI to link to your channel.

Another good proof: Take any arbitrary rectangle. Find it's center. By definition, all 4 corners will be the same distance from the center. That means a circle can be draw with the same center, passing thru all 4 corners. Now the corners of a rectangle are 90°. Diagonals of the rectangle are also diameters of the circle, so 2 opposite corners form AB, while either of the other corners is P, as per Eddie's diagram.

You can also reverse it, taking Eddies diagram and extending PO to Q of the far side, forming 2 crossed diagonals, which also define a rectangle.

What program are you doing all of this work in? Seems very helpful.

Nice elegant proof of Thales' Theorem.

Circle Geometry is one of six topics covered in the Western Australian Mathematics Specialist ATAR course in Year 11. We covered 12 circle theorems, with this being one of them. Problems in assessments and exams were typically either deductions of angle sizes or chord lengths, or proofs using some of the theorems.
It's sad to see this topic not as prevalent in the HSC Mathematics courses as it was a pretty unique and interesting part of our top mathematics ATAR course.

Man I wish I had you around when I was studying math in college.

[VihaanBelani]

Can you please solve some of the Maths problems from JEE exams(it's one of the toughest exams in the world and is an entrance exam in India)

bro just be teaching fr (i am going to do it)

[syedhasanabbaszaidi]

I always feel a little bit smarter after watching an Eddie Woo video.
