In this video I go through some past papers on Circle Geometry with my online CSEC Maths Class. Online CSEC Maths, Chemistry, Physics Lessons 868-784-2059
min. 1:07:05 BOE=360-BOE: =360-140=220(REFLEX ANGLE), Then BFE is 1/2 (220) =110 A cord makes 2 segment in a circle. Remember you can apply the theorem of 'angle at the centre is twice the angle at the circumference,' for minor and major arcs as well.
I watched a lot of circle theorem videos & this video is the first one that I can say that I completely understand circle theorem.
Excellent.
for reallllll
Good explaination sir
Thank you so much sir for helping us. By far one of the best teachers out there.
Totally agreed
Facts
Anyone here in 2024? 😅
Yessir
😂here...private candidate
Ma ppl (ಥ﹏ಥ)
ofc😂
Yey
Exam in 2 days paper 2😢 anyone else?
same

Can someone explain what will be the reason for OAF for the 2013 question
For question 1(iii) I used the Alternate Segment Theorem to get my answer which was the same 32. Would it be corrects in terms of reasoning?
yes it would be correct
I was thinking that same thing sir Thank You!
Thanks sir, this was extremely helpful.
Glad it helped
thank you so much I feel much more confident for these type questions🤭👏
Thank you very much it really helped me a lot
Glad it helped
helpful... thanks
how do i access the papers thank you
couldn't the reason for JGH be the same as JHE ?(the angle in a semi circle is 90 degrees)
Opposite angles in cyclic quadrilateral are supplementary CMB =180-58=122
thank you so much for this sir, really really helpful
Sir are you doing any revisions for January exams
Is there any way that I could get the questions?
Ok this is basically O level question which is quite easy
FGH=68 the reason the angle made by a tangent and chord is segment
JHE is the angle between a tangent and. Chord is 90°
Reason the angle in semi circle is 90° , Angle ABC = 180-(58+90)=32°
Angle at the center is twice the angle at circumference
Hello
Opposite angles in a cyclic quadrilateral are supplementary
50 reason the angle of centre is twice on the circumference
The angle between a tangent and chord is same
A chord involve and tangent are the same touching a point A
I used alternate segment theorem for may 2013 OAF and got 55.
The angle in a semi circle is 90°
Yes sir the question before you just flip it to get our answer
Thank u so much 🥰
Opposite angles in a cyclic quadilateral supplementry
The angle in a semi circle Angel AbC = 180- 90+58 = 32
90+58 = 148 180-148 =32
I wanna join your class sir
CMB = 180-58=122° my reason the angles are cyclic quadrilateral
Cyclic quadilateral a+c =180 b+d= 180
SOQ=2×58=116° , SO=OQ=radius
There no working NCM is also 32° is right angle triangles
UVY= Angles in the same segment are equal
180-(90+58)=32 and also a right angle triangle
Angel is ABC = 180-(90+58)=32°
180-116= 64/2 =32
thank you very much indeed
You are very welcome
Thank you idk what I would have done 😭
Good morning sir
This is becoming hella easy to do...with practice...
CMN=180-(58+90)=32°
FAB =180-(75+50)=55°
Right angle triangle 90°
NCM is 180(58+90)=32
Afternoon sir
helpful... thanks
NCM=180-(58+90)=32
OQS= 180-116/2=32 because issoless triangle
thank you sir
Afternoon sir and classmates
CMB is 180-58 = 122
EO =OB radius =180-(20+20)=140
RSPQ= cyclic qraudrilateral
SPQ= 180-58=122°
Thanks a lot sir
Most welcome
Why not drawn to scale? , not good
TSR=180-56=124°
🙏🙏👍👍
Right angle triangle
