Proof of the Circle Theorems

I am speechless, This guy is a pure genius. Thanks a lot sir. You are helping us to get better in maths

@14:09 could you have included the step where you expanded out 1/2(360-x), just for slow thinkers like me ? 😅. Really enjoying trying to get these proofs by myself by pausing the video and having a go!

[@paulastreet4557]

For the fourth proof (the proof that opposite angles in a cyclic quadrilateral add to 180 degrees) I'm not sure how you know which centre angle you use (i.e. x or 360-x). Except that when I turn it upside-down, I can see how 360-x would be the angle to compare with ABD....so, having done that, it's obviously true that the other centre angle must belong to the opposite angle to the one I 'got'!

[@MANTRA_OP-X]

This is redundancy, you can say simply that BCA=y+x But A+B+C=180 degrees Then C+C=180 :C=90degrees That's it

[@nighttrain1236]

Your method for number one uses a circle theorem for its proof; two radii form an isosceles triangle. I though we weren't supposed to use circle theorems to prove circle theorems unless instructed? I've very confused how to answer #1 properly now.

[@RobertLeversyt]

He did not use multiple radii, he used a singular radius to construct them both.

[@Jaffacakemf]

This is fr so helpful I ignored circle theorems like all year and now my paper 2 is in less than a week lol

[@LightYagami22886]

for the first proof, can I say ACB is at the circumference and angle AOB is at the centre while it is 180 degrees. If I use angle at the centre is twice as angle at the circumference, then angle ACB is half of 180 which is 90 degrees and it is a right angle.

no bc u cant use theorem rules

[@Ahmedhassan-rq8ny]

wouldnt you say for q1 that angle opposite the diameter = 90

For the last proof, I had paused the video a couple of times and ALMOST got there (I got to the point of realising that it was about angles in a triangle adding up to 180) - but I took so long that I forgot that the question asked for proof re angle ABC!
