This can be proved : in ∆abc and ∆cda, Ac=Ac(common) Ab=cd(given) Bc=ad(given) Therefore,∆abc congrenct ∆cda So,angel 3=angel 4(cpct) I.e, ac bisects Angela c ii,we proved that ∆abc congrence ∆cda Therefore bc=cd(cpct)-1 ab=ad(cpct)-2 Ab=cd(given)-3 Bc=ad(given)-4 From 1,2,3,4 Ab=bc=cd=ad Hence proved 😊
Bhai 1 theorem bhi Hai😅😅... Hum answer ko simply is Tarah bhi likh sakte hai:- (i)Since diagonals of a parallelogram divides it into two congruent triangles Therefore, 🔺️ABC≡🔺️ADC Therefore, angle 3=4 [By CPCT] 😂😂😅😶
I am extremely thank you for you sir your explanation is so easy which made this hard chapter extremely easy I really like the way you didn't complicated the things like other teachers you explained this question very easily which made us understand this good❤
Quadrilateral is very hard chapter I can't understand easily but I try to understand it from you sir ❤ I have study whole 8th from you without tution and I scored 93% now I have studied half 9th from you ..❤❤❤ you are best teacher ever 🥰
Sir ji aap 9 class ka science ke uploaded karona gravitational chapter😢😢 please sir mujhe aapka padhya hua samajh aata please uploaded science chapter videos😢😢 aap.bahut bahut bahut bahut badhai padhate hain 😢😢
Sir aapko main really bol raha hun mere ko school ka padhaai nahin samajh mein aata tuition ka bhi nhi aata sirf appka ek video dekh liya bs Mera doubt pura clear ho jata hai
4:30 kya sir isme triangle adc and bca ko congruent prove krke by sss angle 3 aur angle 4 ko equal kr skte hai by cpct , please reply monday is my exam on 16 december
I want to give one advice that i think you have to use white board instead of white sheets , because there is wastage of lots of paper , if you are comfortable to bring it then i think it is good , sir that's your choice if you are able to bring it then alright otherwise no problem By the way Thankyou so much for this wonderful explanation 😊
no because to congruent we need to prove that AB = DC and AD=BC but it is not given that these sides are equal .....but we have to prove these sides are equal in 2nd part of the question ..okay
I don't think so Because, if AC bisects angle A that means angle CAB = CAD and we can see that in these triangles AC is the common side and it's given that the quadrilateral is a parallelogram so it's obvious that AB is parallel and equal to DC and same way DA and CB SAS criteria can be used
@@ananyaarya5147 yes you are right but if this is given then why the question is asking to show that ABCD is a rhombus if all the sides are equal then the 2nd part of the question would be removed na.....also according to your method it would be a long process beacuse bisects mean to prove both the angles 90 and to prove that we would have to do a longgggggggggg processs......by the way you are right you could also solve this question by your process :-)
@@ananyaarya5147 yes your method is definitely correct but it is gonna be a long method and sir suggested us a short one so you may use whatever methods you wanna use it depends on you whether right or wrong..i just answered your question ..okay...that's it i don't wanna debate on it more....have a good day and good future and all the best for all your upcoming exams.....nice to talk you....goodbye :-)
sir aap padha acha rhe ho or aapke tareeke se mene q kiya tha paper me but mere marks kut gye pure kyuki teachers ko proof chahiye hota hai hr jagah.....
Lekin rhombus ki parallel sides equal hoti hea agar upar Vali 5cm hea too niche Vali bhi 5cm hogi or agar left Vali 10 cm hea too os kea parallel yani ki right Vali bhi 10 cm hogi
This teacher literally needs to be praised. Earlier I used to hate maths but now I fell love with math's!
really
Even me too

Mai bhi hu 😊😊😊
Par tumhari to shadi ho gai hogi itni badi ho isliye 😂😂😂😂
The way of your teaching is so good . 🙂✌️❤️
Yes
This can be proved : in ∆abc and ∆cda,
Ac=Ac(common)
Ab=cd(given)
Bc=ad(given)
Therefore,∆abc congrenct ∆cda
So,angel 3=angel 4(cpct)
I.e, ac bisects Angela c
ii,we proved that ∆abc congrence ∆cda
Therefore bc=cd(cpct)-1
ab=ad(cpct)-2
Ab=cd(given)-3
Bc=ad(given)-4
From 1,2,3,4
Ab=bc=cd=ad
Hence proved 😊
Good
Kya yeh sahi h ?
bhai y e top 6,7 line me aengle ki jagah angel or anglea kyu likha h
Bhai 1 theorem bhi Hai😅😅...
Hum answer ko simply is Tarah bhi likh sakte hai:-
(i)Since diagonals of a parallelogram divides it into two congruent triangles
Therefore, 🔺️ABC≡🔺️ADC
Therefore, angle 3=4 [By CPCT]

We can congruent that two triangles and by cpct angle 3 =angle 4
And rest sides will also be equal by cpct..
Sir aap bhaut bhaut bhaut acha smajte ho thankyou sir .
Sir very nice explanation 👍🏻👍🏻

Sare achhe teachers UA-cam me hi hai class me itna achhe se koibhi nhi samjhata
Thanks a lot sir for our doubt clear 🙏
Well in the second part we can also prove the two triangles congruent and the give the answer by CPCT.
Thanks sir btw for help.

Sir you can prove the triangles by SSS, OPPOSITE SIDES OF A //GM ARE EQUAL SO AB=CD AND AD=BC AND AC=AC BECAUSE COMMON SO.
Yes bro right
Even I have done this question by congruence
Sir you are good teacher and outstanding 🥰
U are teaching very good sir thank u so much
It helps me a lot
Sir your teaching is very good I can understand more than what our math sir says soooooo thanku sir
Thank you sir ❤❤
Do we also need to proove if the diagonals bisect at right angles ???
No
No only one diagonal is here
No you don't need because if all sides are equal , then automatically digonals will bisect each other at right angles

Sir : kyu ki equal angles ke saamne . Me : kisi ki nahi chalti 3:18
Sir dono triangles ko congrent prove krke cpct se equal prove kr sakte hain..?????
Nahi
sirf ye likh sakte ki by alternate interior angle SE likh sakte ha

Thanku so much sir ji ❤❤❤❤❤
Par sir 4 sides toh ek square ki bhi equal hoti hai thus yeh kaise pata challa ki ABCD ek rohombus hai ki square ??
Lekin rhombus ki parallel sides equal hoti hea agar upar Vali 5cm hea too niche Vali bhi 5cm hogi or agar left Vali 10 cm hea too os kea parallel yani ki right Vali bhi 10 cm hogi
