Friends,
This is a Math video. This is our thirteenth webisode (WB-13) on "Series 7 -- Triangles".
In this video, we learn that if we have a triangle that has two unequal angles, then the side opposite to the greater angle is longer than the side opposite to smaller angle.
Finally, we go ahead and prove this.
This video is suited for class-9 (Class-IX) or grade-9 kids.
Cheers,
Friends at Rising Pearl
Hats off sir fabulous explanation
Hi Malav, you are very kind. Thank you for such a wonderful feedback. I very much appreciate it. Pls do check out some of the videos on my channel as and when you get time and let me know your comments, feedback on those as well. Thanks again! Cheers,
sir your videos are awesome. But in this video, you have used 'Sum of any two sides of a triangle is greater than the third side' theorem, and in 'Sum of any two sides of a triangle is greater than the third side' theorem-proof video you have used this theorem. How does it make sense?
Bro please do it in English.
This is the first video which I watched from you, and I have to tell you, you really saved me, cause I tried to understand it by myself since two days, but I couldn't and the teacher couldn't neither help me. However, you explained it so well that watching it once was enough to understand. thank you
Pls create playlists of triangle theorem
sir, u are teaching well. make it continue..... your channel will be grown sure. thanks
Ram - Thank you for those kind words. I very much appreciate it. Pls like the videos and share them with your friends and help spread the word around about this channel. Thank you again. Cheers,
How can we use the theorem to prove the theorem????
Why we are bisecting the triangle ? Is there law for cutting or bisecting a triangle or we are bisecting it on our own choice??
I also think the same thing
U are right
It is done as per the angle addition postulate.
Thank u very much for the explanation.
Thanks

I am Madhurima and I am 10 years old . Thanks for helping me in maths but in our school there was some questions , I can't understand the questions and don't know the exact answers . Can you help me ? The question is - The side opposite to angle L ______ , The angle opposite to side LN ____, The vertex opposite to side MN _______ , and The side opposite to angle N . Please help me .
Vry nice explanation
Thanks Sunil. I appreciate your feedback. Pls share your feedback on some of the other videos too. Cheers,
Angle should be angle DCB instead Angle ACB I think plz clarify my doubt.
Why are you stop uploading videos plz upload more video because your video is helpful for us
Thank you
You are welcome Satyam. Cheers,
Superb
Right
Yes
Jaibir - Glad you liked the video. Cheers,
Wrong solution
Rishabh Yadav it’s correct
Yeah finally I found someone who thinks like me. The fact that he assumed that d lies in side ac is incorrect as we haven't proved that side opposite to a smaller angle is small.
@@DT-fg9ll He doesn't assume it, he built it that way genius
*Wrong solution*
The fact that he assumed that d lies in side ac is incorrect as we haven't yet proved that side opposite to a smaller angle is small.
That equivalent to proving 2+2=6
By assuming 6-2=4
retard comment xD
Thanks a lot
Abadh - You are very welcome! Cheers,
Explaination not good and it is not clearing all my doubts....
Sir everything is good but ur accent is horrible.
