36:00 instead of solving 3 equations, after we get all 3 vertices A, B and C. Find centroid G. apply OGC = 2:1 i.e. centroid divides ortho and circumcentre in 2 ratio 1. You get Circumcentre, all options have different centres so..done

[veenu]

Teacher with extraordinary skills... You are exeptionally well sir... Advance ke questions bhi halwa bana diye aapne.. #nv sir is great

[its.swayam]

Last question's answer is
Option D:- 4x+3y-8=0

[mrfaisal]

How can anyone teaches us with such a advance level content in You tube at free of cost regularly and also non-stop. ❣️❣️❣️🔥🔥🔥. A huge respect specially for NV Sir 🙏🏽😘.

[evill_killerr]

3:40:46 there we can even find out the centres of each option and check whether it lies b/w 'P' and 'O' or not. Only the centre of option B lies in b/w P and O... :D

[ShubhamVerma-hkqt]

Sir aapne bhot help ki h meri jee ki preparation me
Charan sparsh guru ji
I got DTU Computer engineering 😇😇

[shlokmishra]

NV sir, I would like to thank you for such noble work (teaching) which you are doing. after seeing your one shots I have started feeling confident while solving sums as my all conceptual errors are cleared now. once again thank you very much sir....!!!

[raghuram]

Im following NV sir for my entire maths except Geometry part.. but I have done a mistake.. not listening this geometry part because I already had listened to Sameer sir.. but NV sir is definitely>> Sameer sir.. I'm not saying Sameer sir Is not good. He is also a master piece.. but NV sir explained it further more detailed and simple to understand

[jayeshjoshi]

Thank you so much sir for giving such best content ....

[theseeker]

Love the simplicity and order in your lectures sir. Very grateful.

[sayantanmukherjee_x]

Anyone Who is wondering "So long lectures I would rather complete it in 2-3hr", Big Big blunder because this lectures will build you a beast in mathematics...All magic of our NV Sir🙏👏👏

[arcnemesis]

I saw the live comment section of this lecture and I am shocked by the comments made my people. It is really a question of moral ethics of our society. I don't think this is the place to do things like these. But what a man sir is, he is laser sharped while teaching and ignoring the noise throughout. HUGE RESPECT FOR YOU SIR!!!

[shouryajaiswal]

Thnq so much
For helping with this energetic sessions ❤️❤️❤️👍

[Mishra]

Sir, ,, circle bala chapter mujhe bahut weak lag raha tha but ab bahut confidence feel ho raha hi thank you sir ...🙏🙏🙏🙏💞🌹
