Kills me how excited he sounds as he proves each one I actually love it

Your videos are amazing! Literally all the revision I did for my gcse maths was watch all of your grade 9-4 maths videos on 1.5x speed the night before each paper. I managed to get a grade 9! Thank you 😊

im not going to lie this helped me a lot its 3am in south africa right now and im writing math in a few hours#finals keep doing what youre doing liked commented and shared

[archiesutherland]

i'm going to download most of your videos and watch them on the bus to school

There are some simpler methods but this still really helped

For the right angle in a semicircle question can you just do O = 180 (angle on a straight line equals 180) so ABC = 90 because angle at the circumference is half angle at the center?

Thank u sooo much
Really helped me
Should have seen this channel sooner ❤️❤️❤️❤️😍

Thank you so much. This is so helpful.

good teaching. I have been using the website since year 7 (i am in year 8 now) and this helped me to understand and remember the proofs.

Hey! Do we need to learn all of these proofs for the GCSE Edexcel Maths 9-1 exam? Will there be a proof question on circle theorems in the exam?

[bendoy]

At the moment, the only place where I am losing marks is in the hard problem solving / proofs questions (the ones at the end of the paper that most people aren't able to complete). How would you recommend revising harder problem solving questions in general, given that there isn't much time left and the questions could be based on seemingly anything?

[AIlezAlIezAIIez]

Are there more proof videos on this topic for the other theorems or aren't they necessary to know for edexcel?

On 7:24 how did -1/2x - 1/2y turn into -(1/2x + 1/2y) Im so confused

When asked to prove the 2 angles in the same segment are equal, would we have to show all the proof for 'angle at the centre is double the angles at the circumference'?

[ananhello]

for theorem 1, if centre o is not inside triangle ABC, how don you prove it?

[roadworksahead]

Hi, are these the only proofs that will come up? If i memorise them, will I be good for the exam?? Thanks!

For "Prove that opposite angles in a cyclic quadrilateral sum to 180°", Why couldn´t you use the circle theorem "The angle at the circumference in a semi-circle is 90°"?

[MegaScooter]

Just a quick question, thanks for these videos btw, what software and hardware do you use to write your answers to these exam papers when making these videos? Atm I am printing past papers, but I would like to do them online like you. Thanks!

Since when did Anthony Joshua do math tutorials?
