Pythagoras H W Ans... so apply special case i.e 2 same side then 3rd side will be ×2 so.... (x+1)*2=(2x)*2 + (x-1)*2...=/ x*2+1=4x+x*2-1...now x square and 1 will be cut from both sides (x*2+1=x*2-1) will be cut and well be left with 4x=0 and x=4
In the second last question where we have to find the perimeter of triangle 📐 BCD why we added side AB and AD in that? For perimeter of 📐 BCD we have to calculate BD+BC++CD. Isn't? Can anyone please explain?
55:58 sir question is wrong i think its quadrilateral not triangle if it way triangle then it should have been 4root2 plus 4root2 plus 8 therefore 8root plus 8 as ans of triangle bcd

opt d. 16 + 4√2 not correct,
Perimeter of triangle BCD ans. 4√2+4√2+8
but not available in options
exactly
Assume u have to find perimeter of Abcd
perimeter of triangle BCD = 8 + 8ROOT2
👍
Thanks a lot sir apke vajah se maine ssc cgl nikal liya air 3 ssc
par bhai tu hai kaun
@johncrouse6478 🤣🤣🤣
@ 55:00, Question is asking about Perimeter of Triangle BCD but u have solved for Quadrilateral ABCD.
Sir the question is to find out Perimeter of BCD not ABDC, now i got confused

Correct
very nice video sir . fantastic explanation and the way of teaching.
n ofc ques me clarity badhti ja rhi hai classes bahut helpful hai 🥰😇
@mbawallah 55:53 : The correct answer is 19.3, which is in none of the options.
Yeahhh topper 😅
Sir tips please 😢 how to get 99.1 percentile
sir the third side could also be 9…why did you choose 5 as an answer
According to Pythagoras theorem triplet (3,4,5) x =4
Last Question OP...Sir bhot mast smjha...specially glowng lines.. kller visualisation
The question is to find the perimeter of the triangle , but sir u find the perimeter of the whole quadrilateral! 🤔🤔
@@rahulbathla ohkk sir...I understood , Thank you !
Hello even i have same doubt...Did you got the answer as to why perimeter of whole quadrilateral was found out and not only of triangle BCD?
Me too I have the same doubt, why did the sir found the perimeter of the quadrilateral instead of triangle!
Me 2 have the same doubt??
@@shreyatiwari216 who did you get that ...?
Thanks a lot sir the way you teach is really helpful 👌
In the second last question where we have to find the perimeter of triangle 📐 BCD why we added side AB and AD in that? For perimeter of 📐 BCD we have to calculate BD+BC++CD. Isn't? Can anyone please explain?
@rahulbathla sir please explain..
Sir in last question we could use (tan C) = 3/4 and then find l, m, n
55:58 sir question is wrong i think its quadrilateral not triangle if it way triangle then it should have been 4root2 plus 4root2 plus 8 therefore 8root plus 8 as ans of triangle bcd
Sir parameter Wale question me angle B 90 degree kese hua
Oyee hoyee 🥰
Bade soone lag rahe ho 😇❤️
Hw 2 ans= 4
❤❤❤❤❤❤❤
fantastic lecture
in 2nd last question it has asked for perimeter of triangle
Thank you sir
Sir looking cute in cap♥️♥️
Sir 6 will also a correct answer 😊
Homework Answer sir, 4
Please tell some steps
From which college Rahul sir did his MBA??
IIT ROORKE
4 is the answer
HW.. Answer 4 (b)
can you please explain ?
x=4 ans for homework question
H.w question ans is 4
Hm q2 answer. 4
x = 4 by using theorm
Theorem ki jarurat hi nhi thi 3,4,5 ka triplet hi samjh arha tah
42:50 mene phle hi isse solve krkke 30degree laya y .. ko. ...

small correction in ur 1st line of description sir, VISULAISE nahi its visualize.
bhai tu pdhai kar! Oversmart na ban, small correction wo bhi description part ko mention kar rahi hain
