True
Yes ,a lot
Sir I am preparing for CAT 2023 , your videos helps me a lot in clearing my doubts . Thank you sir❤️ Keep uploading the best material for us.
howzz your prep going . I am aloso referring to his videos
@@mridulsharma06 it's going great just in between you need to change strategy. For example: giving time to weak subjects at once. And finding your errors and correcting that.
What percentile you got brother??
Thank you very much, sir 🙏 🎉
In pyth. Tri.even number 20 how to calculate
It can be 4 times of 5-12-13
thankyou sir 😇
Hello Ravi Prakash bhaiya!
In these times where everybody just wants to loot money by teaching CAT related stuff, you have been teaching us better for free and I personally respect you a lot!
Thank you so much for doing so. Lots of love!!
Thankyou sooo much sir for bringing such a nice content which covers everything related to cat All for FREE..God bless you
All the best
The formation of pythagorean triplet concept is just fabulous. Never heard about it before. Kudos to you sir!!
Are these lectures useful for 2023 also
Yes for concept building you can use and applied them on simcat test series or any other brand which you want.
concepts never rust@@endsk2436
20 21 29 how are they triplets using your formula 20 square= 400/4 = 100 so 99 and 101 should come???
20^2+99^2=101^2
Works only on ODD numbers.
this trick to remember triplet is amazing, i always used t wonder how people remember so much, thanks thanks thankssss a lot.!!!
What was your score?
For even - if I sq. 20 its 400 and now if divide it by 4 its 100. Now if i take the av. of the two consecutive no. then it should be 99 and 101, right? but its 21 and 29, could you plzz explain this sir
20×20=400
99*99=9801
9081+400=1021
And 101*101=1021
According to uuu 20,21,29 are also triplet
@@josephrajanaind3328 it is
Both are true brother
Thank uu sir for your support.....it is very helpful for those students who can't afford coaching
Relax guys every one have question that if we apply last funda in 20 it's gives us result of 99 and 100 i.e (20, 99,101) but another triplet of 20 is (20, 21,29) soo both are satisfy the situation of Pythagorean triplets.
In the last question where we are supposed to find R and r, we are already given a b and c. SO can't we just use r = (a+b-c)/2 ? That will also give the correct answer for finding 'r' ?
r = a+b+c/2 - h also
Sir in case of 20 the consecutive sides would be 99 and 101 right according to that way
yes, of course
Same doubt..20 doesn't satisfies here..
It is correct,
101*101=10201
99*99=9801
20*20=400
ie. 101*101=99*99+20*20
Topic:-pythagonean triplet's
Q) Sides of a triangle are 15,36,39. Area=?.
In that you have checked whether right angled triangle are not but you haven't find the area .So, can u find that
Half X Base X Height.....aage ka easy hai
Half X _ X _ (just take the 2 small values....so that we eliminate hypotenuse )
@@chiragchaudhari6188 thank you 🌹
Sir 20, 21, 29 and 20, 99, 101 both are satisfying Pythagoras theorem...but according to your formula the former values can't be obtained ...can u or anyone else here please explain why
It is a thumb rule it is not supposed be an exhaustive list
🤔🤔,
Both can work, it will be based on the data given in the question
I don't have word to thank you sir.... I'm really loving your teaching and hats off to you. I would say best teacher on your RUclips today who don't even say.... Not even a single time...to share like or subscribe.....
Sir, Time and work's only 3 lecture are available. Can you please help me in it..? Sir, please upload next videos or if you have made another video of it. Please guide me.
what u are teaching is great stuff that for free
u have all the blessings sir
may god makes u live longer
Sir is teaching brahma triplets 😅
Hi Ravi sir, Will this playlist be enough for GMAT prep also @rodha
thankyou sir..............
Sir amazing concept. I am just fall in love with the way you teaching.❤️❤️❤️❤️♥️♥️♥️♥️
Sir, you're the best and I love your classes. But can you do something about the volume of that intro sound? It hurts my ears every time I move on to the next video..😁😁
Master peace method for triplet
Amazing sir❤❤❤❤
Sir why orthocentre of a right triangle is at its 90 degree vertex? it can also be inside the triangle, since perpendicular of all the sides intersect inside the triangle aswell.
Sir, I think the last question has 2.5 as the height, not 5. And therefore, r=s-h, r=6-2.5, r=3.5.
Please correct me if I am wrong!
Hypotenuse is 5 so s-h is equal to 6-5 i.e 1
@@shivamdrolia600 thanks! I've realized.
Very calm and composed teaching liked it subscribed it

Your content is a blessing. Thank you!
Sir the Incentre and Circumcentre are the same point in a right angle triangle?

trick for finding pythogrean triplets when even is failing for case 20,. 20square = 400/4 = 100.
aa toh raha hai.
99 square + 20 square = 101 square
@@lmaolmaolmaoxd yes
Thank you sir for this, you are honestly the best!
Too much info to process but thank you so much sir
🥰🥰🥰
Thank you sir for these tricks!!
On 11.20 min (a+c-b)/2 you convert into (a+c+b)/2 how? if you are taking one +ve b or chnaging the sign it will effect on equation or what i am missing. please guide anyone
+1... yes how?
-b taken is outside the fraction, so when calculated it becomes (a+b+c-2b)/2= (a+c-b)/2
@@pallabibasu1733 got it 👍
@@pallabibasu1733 i still dint get tis can
Sir In the last question of eqn. Why can't we apply trick of even triplets? By that 144/4 = 36 i.e avg of 37 and 35 therefore c = 37 by that way since c is largest i. e hypo ?
Thank you so much sir for such informative and CAT cracking knowledges. I didn't know anything about this Pythagoras Formation Tricks. Thanks a ton!
Why not 20 21 29 triplet is satisfying the condition of formation of even no. Triplet. Is there any exception for no.s ending with 0 ?
Bcoz 20 is an even number
A no. can have more than one pythagorean triplets.
Best teacher I have ever seen.❤️
⭐️⭐️⭐️⭐️⭐️⭐️⭐️ Right angle triangle
easy formula to find inradius = base + perpendicular - hypo./2
i am so great full you upload videos sir... thank you so much
sir please provide us formula sheet for geometry 🙏🙏
sir, same trick of even triplets doesn't work for 20,21,29
Thank You sir
Thankyou sir !
At 7.50 how came B and internediate point equal to r
Sir we can do for odd no. (n²±1/2)
For even no. ( n²/4±1 )
thanks a lot sir
Amazing concept sir! You make maths fun!
20,21 & 29 Pythagoras triplets
you are not just a teacher but also you are god of math tricks
wish I had seen Rodha at beginning of this year
ABC is a triangle with 3,4,5 respectively.find the radius of circumcircle and incircle.?
Circumcircle 2.5,incircle 1
excellent learning experience
Awsome❤️
🎉❤
Thank you side.
Very good content🤗🤗
don't know how to thank you sir
In radius equals semiperimeter minus inradius
Thankyou sir. U r my inspiration to crack CAT
amazing teaching sir
Thank you so much sir.❤❤
i will break cat 2022
Thank you sir 🙏

jw nice concept ..
Loved ur videos ❤🎉
Thank you sir
Thank you sir
You're the best
Can anyone tell me how extra b came at 11:50
Think like to +b/2 extra, -b/2 (already in eqaution) = x+b/2( that he added to get "s") then you'll get x =-2b/2 = -b
@@kavyapande4886 I think he just did it for the sake of getting the answer based on that formula and what you're saying is out of context I guess, because Aap ek aur b/2 kis basis pe add kroge?
@@devarshisharma1033
Extra kuchh nhi add kiya h maine, sir did that to get r in terms of s. I know that. I was just telling mamodo where he took extra b from. That was to get r in terms of s.
May be I was not so clear in that explanation 😅
@@kavyapande4886 okay 👍🏻
Thanku sir

cad ke liya nhi hai bhai ye
👍
AMAZING
14:50 sir here 20 is even triplet....
According to the rule of even we have to divide vth 4.....
But u wrote 20-21-29
That will also form a triplet. There can be more than 1 triplet
@@Rodha thanq u sir......🙏
Sir I completely dependended on u @Rodha
