Im using this guy for my GCSES, much better than my teacher. You are helping students get the grades they deserve!
edit:results day. I got a grade 8 for my maths gcse. Thank you Maths Genie!

I've been trying to understand this for months... You've just explained it in a 10 minute video, thanks so much 😭

[mathsgenie]

Yeah I will definitely have a look at doing that this weekend. Thank you for your comments.

My maths teacher uses your videos to explain things in lessons so he doesn’t have to do it himself

This channel is absolutely saving my life rn

anything.

Theorem 6 that "2 radii make an isosceles triangle" is absolutely true because radius in the same circle is always the same (the property of the isosceles triangle) :))))

My teacher is good at explaining but I'm still watching to refresh my mind. Thanks!

[sanchitasrivastava]

Thanks for such a nice video. It has now become very easy for me to understand this topic

[chuck]

coolstuff! i noticed on that last one, we could also just halve 55 when we knew it and the missing angle shared endpoints. learned from your lesson. thanks!

For future reference. Could you clarify the rules for what qualifies as a cyclic quadrilateral? because all the vertices have to touch the circle and the quadrilateral inside doesn't count as one. So it's very easy to apply the wrong rules when finding the angle. Thanks

Thank you so much, you're literally saving my life❤️

Thanks for sharing this video. I find it very helpful. You explained well and worked through the examples brilliantly.

"Angles in the same segment are equal"
"Angles in a semi circle are always 90deg"
These are basically the same theorem; the segment in the semi-circle is the diameter. I've neither tested nor researched this, but I'm willing to bet that if you had a segment that was half the diameter, the angle produced would be 45deg.
