H/w question ABCD is a quadrilateral In which p is point on AB Q is point on AD R is point on DC S is point on BC Ab = 6cm BC= 9cm CD= 8cm If DR = x Rc = 8-x : BC = 8-x If Ap = x Bs = 6-x Bc = 9 Bc = Bs + Sc 9= 8-x+6-x 9=14-2x 2x=14-9 X= 5/2 AD = X+X AD = 5/2 +5/2 AD = 10/2 AD = 5cm 😅😅 I solved it different then the other guy
21:20 sir in the question CD=12cm but you had taken AC=12cm... Please tell how to do it if CD=12cm or there was an error in the question..... Please do the revision of all the chapters.... Thank you sir ❤❤❤❤❤
AB = 6 cm, BC = 9 cm, CD = 8 cm. Let P, Q, R, S be the points where the tangent touches the sides AD, AB, BC, and CD respectively. P R From a point outside of a circle, two tangents to the circle are always equal. Q Therefore, DP = DS AP = AQ BR = BQ CR = CS Thus, adding the left sides and right sides separately and equating them, we get: (DP + AP) + (BR + CR) = (DS + CS) + (AQ + BQ) ⇒ AD + BC = CD + AB ⇒ AD = CD + AB - BC = 8 + 6 - 9 = 5 ∴ AD = 5 cm. SIR PLZ DO AREA RELATED TO CRICLES
Sir last question mai ese toh AP and BP are the tangents from the same external point so they both must be equal.. So BP simply comes out to be 12 cm.... Then why we used Pythagoras theorem there???
@@shvetasood1) Tangents would have been equal if they touched the same circle 2) But the tangents from an external point are touching two different circles. So here theorem will not be applied. 👍

Sir 45.44 pe 18 ke jagah 27 ayega jiski wajah se answer 10.5 ayega
Yaa Exactly Broo🤔
45:34 wrong ans 😢😢
41:44
AB + CD = AD + BC
6+ 8 = AD+9
AD = 5cm
21:17 sir i think u r mistaken ..
CD ki length given h AC ki nhi
45:39 sir, 9×3=27 not 18
Ans will be 7 i guess of x
@@OFFICIAL_AKJno it’s 10.5
H/w question
ABCD is a quadrilateral
In which p is point on AB
Q is point on AD
R is point on DC
S is point on BC
Ab = 6cm
BC= 9cm
CD= 8cm
If DR = x
Rc = 8-x
: BC = 8-x
If Ap = x
Bs = 6-x
Bc = 9
Bc = Bs + Sc
9= 8-x+6-x
9=14-2x
2x=14-9
X= 5/2
AD = X+X
AD = 5/2 +5/2
AD = 10/2
AD = 5cm 😅😅
I solved it different then the other guy

21:20 sir in the question CD=12cm but you had taken AC=12cm...
Please tell how to do it if CD=12cm or there was an error in the question.....
Please do the revision of all the chapters....
Thank you sir ❤❤❤❤❤
Yes
It was an error as there was a triangle in the figure so it cannot have the side CD
Use pythagoras theorem and find the value of CA
Because AD=5, CD=12, CA=
BY PYTHAGORAS THEOREM
@@narsinghyadav7185 means you dumb is saying that hypotenues in smaller than parpandicular
41:46 , sir the homework question's answer is 5cm.
21:17 sir in the question it is written CD=12 cm while u have marked AC as 12 cm...
Yess
Sir Apne Question Easy Diye Ho Ya Hamme Easy Lag Rha Hai..
Vaise Thank You Sir Very Much..
AB = 6 cm, BC = 9 cm, CD = 8 cm.
Let P, Q, R, S be the points where the tangent touches the sides AD, AB, BC, and CD respectively. P R
From a point outside of a circle, two tangents to the circle are always equal. Q
Therefore, DP = DS
AP = AQ
BR = BQ
CR = CS
Thus, adding the left sides and right sides separately and equating them, we get:
(DP + AP) + (BR + CR) = (DS + CS) + (AQ + BQ)
⇒ AD + BC = CD + AB
⇒ AD = CD + AB - BC
= 8 + 6 - 9
= 5
∴ AD = 5 cm.

Thank you so much sir wese to mere pas basic maths hai par sare questions karke bohot acha laga
46:33 wrong answer
Right is 10.5❤
41:39 Answer: AD = 5 cm
54:50 Ans= √160
sir ap is equal to bp then it is 12 cm right 55:27
30:33 ans 11 aana chahiye 27 mai 14 add krke 38 nhi aata
Sir AD is 5cm in (homework question)
sir 21:48 question me CD 12 hai AC nahi
is this for basic students?? this type of easy questions come in standard ???
Sir jii board main acche number layenge apse Vada hai 😊❤
Haaa bhai
Mee too ❤😊
Ha

Me too bro
Sir last question mai ese toh AP and BP are the tangents from the same external point so they both must be equal.. So BP simply comes out to be 12 cm.... Then why we used Pythagoras theorem there???
There are two circles within that diagram, check once then it would be clear to you 👍
@@Naviispeakss but the thing is .. Both tangents are drawn from the same external point
@@shvetasood yes I agree, but the two tangents are intersecting the two different circles of the diagram not the same circle, analysis again..
@@shvetasood1) Tangents would have been equal if they touched the same circle
2) But the tangents from an external point are touching two different circles. So here theorem will not be applied. 👍
46:33 ans is 10.5

8:22 sir iss triangle ko phle right angled triangle prove karna jaruri nahi hai kya ?
Sir A.P. ke important ques. Krado
AB+DC=AD+CB
6cm+8cm=AD+9cm
14cm=AD+9cm
14cm-9cm=AD
AD=5cm
AD=5cm
we can write this ad+bc=ab+cd directly or is there any solution for getting this?
50:10 Sir AOC and BOD is not a line... So how Angle AOD And Angle BOC are vertically opp. Angles...???
Abhi Vatika protest angle Nahin Piyo Sunday
AP= 9cm
sir you are the best teacher
your channel give free education and in also their is very cheap amount of rupee in paid batchess
thankyu sirrrr
41:43 ans 45cm
5cm hai bhai 😂
Awesome 👍
AD is = 5cm
Nice lecture sir I slove all the questions and all questions are easy and important thank you ❤❤❤❤❤
21:41 mein CD=12 hai not AC=12
AD = 5 cm
AB+CD=AD +BC
41:33 5 cm
Good work sir tnx for helping
Your best teacher
Sir chapter 11 or 12 bhi kara do please 🙏
54:05 instantly pause and watch face
Abe bhai yahi krta h kya 😂
😂😂
radius of circle = 11 cm
4√10 cm for BP value
Last ques....
In Triangle OAP :
By pythagoras theorem:
OP² = OA² + PA²
OP² = (5)² + (12)²
OP² = 25 + 144
OP = 13cm
In ∆OBP:
Again By pythagoras theorem:
: OP² = PB² - OB²
OP² = (13)² - (3)²
OP² = 169 - 9
OP = √160cm...
