All GCSE circle theorems & proofs

In this video I go over the eight circle theorems you need to know for GCSE mathematics, and also provide proofs. Below are the pdfs of the proofs and a blank document that you might want to use to write your own proofs or to help with revision.

00:00 - angle at the centre is twice the angle at the circumference
3:48 - angles subtended by the same arc are equal
6:09 - the angle in a semi-circle is 90 degrees
8:48 - opposite angles in a cyclic quadrilateral add up to 180 degrees
10:37 - the perpendicular bisector to a chord bisects the chord
13:02 - the angle between a tangent and radius is 90 degrees
16:13 - tangents from a point are equal in length
17:46 - alternate segment theorem

not @ me watching this the DAY before the maths test ✨☀️🌟💫💜🥺💖🧚‍♀️🌈🙈

[@letsimage]

thanks a lot for explanation! especially for angle in a semicircle!

[@nstar3489]

I was literally going to revise this so tsym!

[@mano8783]

thank you so much, really appreciate it

[@ahmadjawadeosmani8948]

I know every one except alternate segment theorem.Thanks

THANK YOU!

Students: Want to do well in Maths ! Alternate Segment Theorem: I'M ABOUT TO END THIS STUD'S WHOLE CAREER !!!

Iulius Constant Cornelio I dont understand what’s so hard about it😂

[@iuliusconstantcornelio2018]

@@MrSeful94 Haha, very funny !

[@iuliusconstantcornelio2018]

@@MrSeful94 If you would think from the perspective of other students, not only yours, you'll find out most students find that theorem the most challenging out of all the other ones !

Angles in alternate segment are equal.

whats the music name at the end?

First view and comment 😁😁😁

[@omarmahmood1155]

5:37 it says the opposite thing on the second theorem and at 8:47 it says the opposite 🤨

[@maths.explained]

Yeah I messed up the second one and had to record it again 😬

[@omarmahmood1155]

Maths Explained, so at the end, is the centre half or twice the size of the angle at circumference? Ps. Sorry for not letting that subtle mistake go through, what can I do when I have that Eagle sight 😎

[@maths.explained]

haha no problem. I consider them "easter eggs"

[@mrcheese1373]

Guys are the videos from 2006 really helping ?

[@PlayerCC]

Yes
