CSEC Maths - Circle Geometry Past Papers

[@leahbishop1117]

I watched a lot of circle theorem videos & this video is the first one that I can say that I completely understand circle theorem.

[@CSECMathematics]

Excellent.

[@MontellJacobs-o4w]

for reallllll

[@MutintaChitendele]

Good explaination sir

[@jaden2446]

Thank you so much sir for helping us. By far one of the best teachers out there.

[@relaxgirl5129]

Totally agreed

[@kellyyy1333]

Facts

[@LEOYT_BABBY]

Exam in 2 days paper 2😢 anyone else?

[@abayomisylvester6838]

same

[@VasileFlorinSenciuc]

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.

[@clipville00]

Anyone here in 2024? 😅

[@5thdimentionalbeing367]

Yessir

[@SusanDomingo-f7e]

😂here...private candidate

[@marianewman8638]

Ma ppl (ಥ﹏ಥ)

[@Dxspair.]

ofc😂

[@neikahannam8385]

Yey

[@jeleelad.4021]

Thanks sir, this was extremely helpful.

[@CSECMathematics]

Glad it helped

[@isatujalloh552]

Thank you very much it really helped me a lot

[@CSECMathematics]

Glad it helped

[@bensonnyondo8691]

helpful... thanks

[@JellyJay.]

thank you so much I feel much more confident for these type questions🤭👏

[@desiwidthalocs]

thank you so much for this sir, really really helpful

[@ayannalewis8470]

Opposite angles in cyclic quadrilateral are supplementary CMB =180-58=122

[@gaminghellfire]

Ok this is basically O level question which is quite easy

[@Jadeweast]

So when trying to find the missing angle in a isosceles triangle, we add and divide by 2?

[@ayannalewis8470]

Angle at the center is twice the angle at circumference

[@tantanwilson6183]

Hello

[@ayannalewis8470]

JHE is the angle between a tangent and. Chord is 90°

[@TheNikbel]

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?

[@jaden2446]

yes it would be correct

[@lenicebethelmy7648]

I was thinking that same thing sir Thank You!

[@thatguyfrom-yx8pk]

I used alternate segment theorem for may 2013 OAF and got 55.

[@ayannalewis8470]

Reason the angle in semi circle is 90° , Angle ABC = 180-(58+90)=32°

[@ayannalewis8470]

Yes sir the question before you just flip it to get our answer

[@silas533]

Can someone explain what will be the reason for OAF for the 2013 question

[@ayannalewis8470]

FGH=68 the reason the angle made by a tangent and chord is segment

[@ayannalewis8470]

Opposite angles in a cyclic quadrilateral are supplementary

[@novisheensalinel7264]

Thank u so much 🥰

[@ayannalewis8470]

The angle in a semi circle Angel AbC = 180- 90+58 = 32

[@myaben4366]

90+58 = 148 180-148 =32

[@ayannalewis8470]

Opposite angles in a cyclic quadilateral supplementry

[@PreciousGeorge-uo9nm]

Sir are you doing any revisions for January exams

[@kellybrownnelson2947]

Thank you idk what I would have done 😭

[@ayannalewis8470]

A chord involve and tangent are the same touching a point A

[@jeanettelee5608]

thank you sir

[@sitisunny6058]

couldn't the reason for JGH be the same as JHE ?(the angle in a semi circle is 90 degrees)

[@ayannalewis8470]

Afternoon sir and classmates

[@ayannalewis8470]

50 reason the angle of centre is twice on the circumference

[@ayannalewis8470]

Afternoon sir

[@ayannalewis8470]

SOQ=2×58=116° , SO=OQ=radius

[@ayannalewis8470]

The angle in a semi circle is 90°

[@ayannalewis8470]

180-(90+58)=32 and also a right angle triangle

[@ayannalewis8470]

Good morning sir

[@r.s9643]

Thanks a lot sir

[@CSECMathematics]

Most welcome

[@Caribbean_Doll500]

how do i access the papers thank you

[@ayannalewis8470]

UVY= Angles in the same segment are equal

[@ayannalewis8470]

Angel is ABC = 180-(90+58)=32°

[@adgf1x]

[@bensonnyondo8691]

helpful... thanks

[@ayannalewis8470]

The angle between a tangent and chord is same

[@silxbeats]

This is becoming hella easy to do...with practice...

[@ayannalewis8470]

Cyclic quadilateral a+c =180 b+d= 180

[@adgf1x]

[@jouvanayholloway4960]

Is there any way that I could get the questions?

[@ayannalewis8470]

EO =OB radius =180-(20+20)=140

[@adgf1x]

[@ayannalewis8470]

OQS= 180-116/2=32 because issoless triangle

[@andreinadelacruz1022]

[@1973yogesh]

🙏🙏👍👍

[@bintubarre2680]

I wanna join your class sir

[@Jadeweast]

The last one? Confusing bad

[@ayannalewis8470]

CMB = 180-58=122° my reason the angles are cyclic quadrilateral

CMN=180-(58+90)=32°

[@ayannalewis8470]

FAB =180-(75+50)=55°

Right angle triangle 90°

[@ayannalewis8470]

NCM=180-(58+90)=32

[@ayannalewis8470]

Right angle triangle

[@ayannalewis8470]

There no working NCM is also 32° is right angle triangles

[@ayannalewis8470]

RSPQ= cyclic qraudrilateral

[@francois8422]

Why not drawn to scale? , not good

[@ayannalewis8470]

Angel 180-58=122

[@ayannalewis8470]

AB is a chord
