This is so useful but what do we do if the question states not to use any circle theorums in our answer? Do we just do the same steps of working out but not give the reason why (as giving the reason why often involves stating a circle theorum usually) please let me know thanj you

would they combine circle theorems and ask you to prove it in that way or only single ones like in the video? Thank you!

@1stClassMaths 2 ай бұрын

I'd expect just a single theorem.

Thanks, I found your proofs very clear. A small help to remember, would be to include the name of the theorem written under the main heading?

@MrCrytpic 2 ай бұрын

Are these all the circle theorems for Edexcel?

@1stClassMaths 2 ай бұрын

Technically there is also the radius bisecting a chord at 90°. You can find this theorem in my circle theorem proofs video though. It is seemingly almost never assessed though. I don't actually recall any exam questions using it at all on this specification. You are expected to know it though but it's quite simple.
