Friends,
This is a Math video. This is our sixteenth webisode (WB-16) on "Series 10 - Circles".
In this video, we will learn that the angle subtended by an arc at the center of the circle is twice the amount of angle subtended by the same arc anywhere else on the circle i.e. if an arc subtends an angle "2x" at the center of the circle, then that arc will subtend an angle "x" anywhere else on the same circle. Later in the presentation, we will prove this theorem.
This video is suited for class-9 (Class-IX) or grade-9 kids.
Cheers,
Friends at Rising Pearl
Very simple to understand

Shukriya ustaz 🙏❣️
Many thanks. Good work.
I aced the final exam. Got 4/4 for this question
Hi Sangeetha - You made my day! I am super happy to hear that you aced the finals. Congratulations!!! Cheers,
Thanks
Sir tussi great ho 👏
this is very good video and also very use full thank you sir
Why we can't say that both A and B are on the same segment are equal
Sir aap great hi 🙏
kindly tell me which green board software do you use to write ?
good
Sir remaining part of the circle means the part of the circle leaving the arc (or the part of the circle except the arc) ?
Thanks sir
Hi, You are very welcome! I am glad you liked the video and found it helpful. Cheers,
Hi Ashish,
Thanks, glad you liked the video.
Cheers,
Thanq sir
You are very welcome Shashwat! Cheers,
guys doing a great job. keep it up
Hi Vandana,
Thanks for those kind words. I appreciate it.
Cheers,
sir a median divides a triangle in two triangles of equal area sir a triangle of sides 4,5,6.5.(ABC) it's median AD sir i have calculated it's area first by Herons formula then by drawing perndicular AE and calculated area of its two triangles which is not same as i have calculated by Herons formula why sir
Hi, let us assume that there is a triangle with vertex A at the top and base side BC. Now, we identify the mid-point of BC say D. Then we join A and D. Now, we have two triangles - ABD and ACD. Also, BD = DC. Now, let us drop AE perpendicular to BC. Area of triangle ABD = 1/2 . AE . BD. Area of triangle ACD = 1/2 . AE . DC. Since BD = CD (D is mid-point of BC), both areas must be EQUAL. Can you pls check your work and try again? Cheers,
a really very good video
I recommend you not to do that zoom out and in all the time
Other wise Its a very helpful video.
Zig Zagoon yes
Very slow
But u explain very well
Zig Zagoon Obviously Correct Statement.
This is right
nice video thanks
thanks for this video
d=D
Nice

It will depend on your class and board. For CBSE, this is typically covered in Class-9.
Cheers,
fantastic
hi, plz post a video of chapter surface areas and volume. ..
Rajinder Kaur hello
Ok
Bhai video ko itna zoom in & zoom out kyo karte ho ande nhi he yaar ham🤓🤓🤓🤓🤓
really amazing.......!
may god bless u!
sir to iska measure kaise karenge
This video is a bit long.
Anyways it was easy to understand.
Thanks a lot.
Anyways you say a lot of times "Doston"😀😁😂
okkkkk
Thanks, this helped me to understand the theorem very much :)
it is cool! NOT!!!!
Please show it practically
this video is bery good beacause its presentation is exilent
nice
Sir in exam should we have to prove in all 3 conditions?
Hi Vishad,
Yes. If you have the time, then you should prove the theorem for all 3 scenarios. This is because the arc can be a minor arc, semi-circle or major arc. Hope it helps!
Cheers,
nyc vid . can u plz tell me ur name
Please don't zoom out
Solve this problem jaldi plz sir
Angle subtended by an arc of a circle at its center and at any point on the remaining part of the circle.
1. Objective 2.procedure 3.result
M=mental
A=Attack
T=To
H=Healthy
S=Student
you are big fool can't you proof theorem 3 and4 using RHS congruency
foolish Roy
Put the vedio in 1.25 x speed it will be perfect
very bad bilkul smjh nhi aaya Baar Baar dostoo mt bolo
Aap ki sabhi videos acchi Hoti h but this is bakwas
thanks
what is meant by the angle subtended by major arc ?????
Nice
