let me tell you bros the best people usually tell us to watch their previous videos to clear our concepts but this man right here repeats it in this video itself this mans a legend people hit subscribe
I had commented in the last video that we want lecture of quadrilaterals and you give it today...you are best of any teachers. I was waiting for this video so that I could learn this before it started in our school. Thanks you so much Shobhit bhaiya!!! You are an inspiration to a lot of students.
I do not comment on any video i saw but shobhit bhaiyaa u are just an amazing teacher i ever saw. You're doing ur teaching in mid night from 12:34 to 3:54 just for uss.❤ hatss of to you shobhit bhaiyaa. I understand every point you teach. Your explanation is just too good. I wish that i had a teacher like you in my school. In class i can't understand what the teacher teach but when u teach i understand everything so easily. Thank you so much
Good job brother great but I think from my pov if we say that angle cba = angle bcd so both angle are /3 and as it is a parallelogram after the construction /e=/d so by this we conclude that /3=/4 Is my pov is right reply
shobhit bhaiya you dont know how many students' lives u are saving. literally thank you so much. i hope ye channel reaches millions and all the students study from you! i too am an iit aspirant bhaiya, pls upload how can 9th graders can crack iit starting now
This man is legend he provided us top notes of sci and social and best lecture for class 9 maths toughest chapters and also motivates us and show us right path.salute to you brother🥶
Hello Shobhit Bhaiya! I have been watching your lectures of Lines And Angles, Triangles and Quadrilaterals, it is very fun to study from you and it also cleared my doubts very well. Currently, I am having issues with the chapter Circles, it seems very hard to me and I am not able to understand many of the things in that chapter making me unable to do the questions. Also, many of your viewers want a Circles lecture so it would be really nice if you upload a circles lecture and it would really help me out with my exams since I have a lot of pressure and tension on my head since I am unable to do the chapter Circles. Hopefully you will read this and you will upload a Circles lecture. Again, thank you for such amazing lectures, I am able to perform well because of your amazing explanation. Have a great day!
Shobhit bhaiya salute hai aapko I was struggling hard for this ch and now I'm clear You are a great teacher that you are ignoring (kurbaan) your sleep for our marks and vo bhi bilkul free!!!! Once again salute and tx So jao Varna 3 - Sade 3 Tak jag rahe ho samaj jao aage
This guy is really great because for our sake he is spending whole day but also he is doing his teaching at mid night 12 to 3 am really hatsoff for this man❤
Usually i dont comment sir, but such an exquisite explanation, to be honest, this is the best a student can afford, and i would heartly like to appreciate your efforts ! 👏👏
"DAV school ka student hu, par coaching PW se liya, Lekin Shobit bhaiya ke videos ne padhne ka junoon diya! Lecture aapka dekhta hu, dil se karta hu note, Isliye exam me top karne ka hai mera secret vote!" 😂😂😂😂😂😂😂😂
2:23:06 in 2 part we can do Angle D+ angle 1 = 180 (co int angles). (Eq1) Angle C + angle 2= 180 (co int angles). (Eq2) From eq 1&2 Angle D +angle 1= angle c + angle 2 Angle 1= angle 2 (proved earlier) cancel them out Angle D = Angle C ( proved)
Bhaiya apne jo bhi triangles chapter mein padhaya tha usme se aadhe se jyada questions mere half yearly mein aaye the.or main apki video dekh ke gyi thi mera maths ka exam bahut achha gya Thank you sooooo much bade bhaiya ❤

Bhaiya waiting for Circles and Surface area and volume...kindly make it soon..exams are approaching and you're the only teacher from which I can easily understand math! Thank you so much for everything❤ You really made mathematics a simple subject !
At 02:22:50 , we can prove it by Angle A + D = 180° Angle B + C = 180° (Co. Int.) A + D = B + C As A=B A + D = A + C Angle D = Angle C Easy method, finally I'm doing it myself. You r so good in teaching.🎉
2:23:32 (iii) In triangle ABC and triangle BAD AC=BC(given) , angle 1=angle 2(as proved) , AB=AB(common) So by SAS , Triangle ABC is congruent to triangle BAD. (iv) AC=BD ( by CPCT) Hence proved....😊
First of all, I would take a moment to Thank You for making 9th so tranquil. You will forever be remembered as one of the best mentors of my life, Bhaiyya. Take it as an appeal or request can pl make the next video on Circles, please ASAP.

Shobhit Bhaiya, your video meant the world to me. It's been an absolute game-changer, and I can't thank you enough for your incredible teaching skills. You've made such a difference in my learning journey, and I'm genuinely grateful for everything. ❤️
THANK YOU SOMUCH BHAAYIA FOR A VERY GOOD LECTURE BECAUSE OF YOUR PREVIOUS LECTURES I HAVE SCORED 73/80 IN MY MATHS HALF YEARLY EXAM AND I PROMISED YOU THAT I WILL SCORED 80/80 IN MY MATHS YEARLY EXAM.😇
Hello Sir, I am not sure whether you would see my comment or not,but I have my paper on 2 days after tomorrow so pls make a lecture on circles... It would be really helpful
shobhit bhaiya ek doubt tha, jo question tha "show that bisectors of angles of parallelogram form a rectangle" usme hum directly nhi likh sakte angle PQR equals 90 degree (vertically opposite angles) and then angle P plus angle Q equals 180 (co interior) and then angle R equals 90 (VOA) itni lambi calculation kyu kar rhe hai?
actually, as a fellow student, I think this is so because it has not mentioned in the question ki PQ parallel to RS isliye co interior angles nhi le sakte i guess vo parallel tab prove hoga jab vo rectangle prove hoga .......? well that was my take ,if there is any mistake, feel free to correct me😅..it would be a lot of help...:)
Sir tomorrow is my maths exam and i can't solve the question related to quadrilateral but i can do it now thanks to you sir i want your blessings so i can score 100 out of 100 in my final exam if i get full marks i will give update tomorrow 🎉🎉
Great explanation sir .This explanation was very useful for me as I am having my exams soon .I will always be grateful for this video. Once again thank you!

By which congruence rule part III will be congruent plz answer
2:23:34
(ii) /A+/D = 180° (Co interior )
/B+/C = 180° (co interior )
/A+/D = /B+/C
As /b= /a
/B se /a cut jayega
So, /D = /C
Hence prove (ii)
sahi hain
Good job brother great but I think from my pov if we say that angle cba = angle bcd so both angle are /3 and as it is a parallelogram after the construction /e=/d so by this we conclude that /3=/4
Is my pov is right reply

thanks bhiyak😢
Hello Shobhit Bhaiya! I have been watching your lectures of Lines And Angles, Triangles and Quadrilaterals, it is very fun to study from you and it also cleared my doubts very well. Currently, I am having issues with the chapter Circles, it seems very hard to me and I am not able to understand many of the things in that chapter making me unable to do the questions. Also, many of your viewers want a Circles lecture so it would be really nice if you upload a circles lecture and it would really help me out with my exams since I have a lot of pressure and tension on my head since I am unable to do the chapter Circles. Hopefully you will read this and you will upload a Circles lecture.
Again, thank you for such amazing lectures, I am able to perform well because of your amazing explanation. Have a great day!

Kisko kisko quadrilateral ka intezar thaa ❤❤
2:23:06 in 2 part we can do
Angle D+ angle 1 = 180 (co int angles). (Eq1)
Angle C + angle 2= 180 (co int angles). (Eq2)
From eq 1&2
Angle D +angle 1= angle c + angle 2
Angle 1= angle 2 (proved earlier) cancel them out
Angle D = Angle C ( proved)
After this 3 and 4 are super simple
well done
Thanks for helping 😃
AB parallel to DC nahi hai
Angle A +Angle D =180 nahi hoga
AD parallel to BC hai

I NEEDED THIS SOO MUCH ITS LITERALLY SO ON TIME THANK YOU SOO MUCH
very underrated teacher ,
you deserve a million subscribers for your teaching.
thanks a lot 😁😁🌟🌟😊😊
1:27:41 sir, here we can also use some angle property of a quadrilateral..
2:22:51
Here,in II part,
A+D=B+C+180(Co-interior)
A+D=A+C(Since,A=B)
=> D=C
At 02:22:50 , we can prove it by
Angle A + D = 180°
Angle B + C = 180°
(Co. Int.)
A + D = B + C
As A=B
A + D = A + C
Angle D = Angle C
Easy method, finally I'm doing it myself. You r so good in teaching.🎉

I also did it by the same method it is easier but his method is more professional

1:26:58 Sir yaha pe to ham asani se angle sum property of quadrilateral laga kar bhi kar sakte the na😊
shobhit bhaiya ek doubt tha, jo question tha "show that bisectors of angles of parallelogram form a rectangle" usme hum directly nhi likh sakte angle PQR equals 90 degree (vertically opposite angles) and then angle P plus angle Q equals 180 (co interior) and then angle R equals 90 (VOA)
itni lambi calculation kyu kar rhe hai?
actually, as a fellow student, I think this is so because it has not mentioned in the question ki PQ parallel to RS isliye co interior angles nhi le sakte i guess vo parallel tab prove hoga jab vo rectangle prove hoga .......? well that was my take ,if there is any mistake, feel free to correct me😅..it would be a lot of help...:)
