This is a graphic, simple and memorable way to remember the difference from a chord or a tangent or a segments and sectors! I made this after struggling to understand it myself, once i got to grips with it i decided to help others who were also stuck.. so this video was created…
This video includes Perpendicular bisectors of any chord
the angles in a semi-circle,
what happens when a tangent and a radius meet,
Angles that are in the same segment and how different they are, the circumference subtended by the same arc,
the meaning of subtended,
lengths of two tangents and finally the angle between a tangent and a chord.. aka Alternate Segment Theorem.
I re-uploaded this video because the last one had some glitches so here we are againn….
FOR THE QUESTION IF YOU ARE STUCK
okay so angle A is 55degrees. this is because the whole isosceles triangle adds up to 180degrees, you now take 70degrees from this because the angle on the far right hand side is 70degrees. this leaves us with 110degrees and you divide it by two (due to it being isosceles triangle) so angle A is 55degrees.
if you go to 1:07 this explains the next part on why there is a 90degree angle on top of angle B.
you take 55degrees from that 90degrees because part of the right angle overlaps the first isosceles triangle (on the right hand side) and we have previously worked out that, that angle is 55degrees, this leaves us with 35degrees.
now times that 35 by 2 which gives you 70degrees, take that answer AWAY from 180degrees because as you can see angle D is within ANOTHER isosceles triangle which means all the angles within the triangle add up to 180degrees.
because angle D is within that triangle, angle D and the angle at the bottom right of the Isosceles triangle will EQUAL to the same amount.
now divide the 110degrees by 2 to give you 55degrees.

MUST READ Number six in this video apears to be out of proportion and I did not realise. the arrow head shape MUST join in the centre of the circle not just anywhere. please note that the angle at the CENTRE of the circle is double that at the tip of the arrow.
in the video it is slightly below the centre of the circle.
Please can you do a video on circle theorem, I'm mostly confused
quickly watched this during my zoom call for maths tuition .
really helpfulll
the music is really disrupting
No shut up I aint got a exam tomorrow
Currently, studying what I remembered from my Junior High lessons then hopefully I will pass another entrance exam.
A video that must be seen and downloaded . Great job man !
Thanks Sir
Helpful
but like… how do we solve?
At 1:59, it cyclic not cylic
Hello, I need a help from you. Can you prove that a cyclic parallelogram as a square? I have been trying it for some many months but I couldnt do it. Please help me

I dont understand the last question about d.thanks sir!
Corona took my GCSEs
I wanna know about Euclidean circle geometry
https://youtu.be/wjA03PgwMeM
4 min 11 sec and it says 3 min
thanks! i learned absolutley nothing this whole unit and now i have a test
whats the last one theorem?
Not 3 minutes, 4 minutes
how did you come up with this simplest form of solving circle therom
epic expanation man , thanks❤
just the voice wasn't clear and the music was adding to it.
The 1.2 k dislikes are people who failed the math test
I FINALLY UNDERSTAND CIRCLE THEOREMS!!!!!!!!
wait slowwwwww down 😂😂😂 I understood everything until you brought in arrows and screwed up squares 😂
Helpful but I'm probably will need a video that breaks it down fully☺
Practice questions https://youtu.be/K-XlBqDwwJY circle ques for ssc cgl
faded
Invincible and Faded?
NICE
its ticky but i'll get there
This helped me out a ton on my a level revision thank you.
Thanks sir
Everyone here because of math exams but I'm here because our teacher sent this video for online school 😅
Wow the bgm is Faded!
that make a no sense
Number 8 : AB = AC WHEN B AND C ARE THE POINTS OF CONTACT WITH THE CIRCLE.
You're going to fail your math test, just go watch some TV. Enjoy yourself. There's no reason to try. You're never going to use math in life. Trust me. You're wasting time by trying to studying. Stop stressing and get some rest.
No, i don't have an exam tommorow, Quarantine 🙂
Studying with the music of my fav song ❤️
Best thing eveerr
thanks a lot this video helped me to fully understand the circle theorem.It was a bit challenging topic for me but now it's not
Where's the Quarantine gang at?
