Easier way to solve the problem at 30:00..... whenever the altitude is drawn to the hypotenuse of a right triangle, it is alwasy equal to the geometric mean between the segments in the hypotenuse. So..... CD is the geometric mean of 16 and 4, so CD is 8. Area is (bh)/2.... so the base (16+4) times 8.... and the area is 80.

exactly what i was looking for. you have made my GMAT exam reading easier. thank you.

Very Useful and all properties are explained with excellent technique.. Thank Yo Mr. Gill

Thanks a lot sir. This is one of the most amazing videos related to GRE quantitative section I have come across. I have my GRE this week and this had been amazingly helpful to me!

Hi Sir Your videos are simply fantastic Can you please give me other videos of geometry..I saw on your Chanel that they have been made private . It would help alot if I can get those videos. Thankyou for the amazing work again :)

The voice clarity is perfect. Concepts shown were very helpful Mr. Gill. Thank you.

very informative video!!!. Thank you for sharing

very nice.its easy to learn..........

Made my life hella lot easier.. Appreciate this!!!!

I can't Thank You ENOUGH........... Thank You Very Very much for these videos :)

Good to listen , after i felt it is the area where am uncomfortable.Thanks Phuspinder.

sir thanks good going amazing

Thank u ...so much..ur videos are really amazing.

Great Video Sir!! Neki Kar Aur Dariya Me Daal.. Kind Of Work!! Kudos To You!! God Bless You! Hoping Godspeed For You!:)

Sardarji, you are awesome!

You explain everything so clearly that it sets in mind forever .Always keeps checking if some new topic has been uploaded .. Please cover all topics and help us like this . Thanks!!

really its mind blowing.all the doubts on geomentry are cleared after watching this vedio

pushpinder sir love you u r just awesome many people think that no one can study for CAT without any formal online or offline coaching but u prove them wrong keep it up good going but kindly upload verbal LR videos to

This is a great video. It was a little fast for me, but I learned a lot. Thank you very much.

Excellent !! Thank you so much..

going great!!

Thank You!! You are amazing!

perfact videos

thank you sir thank.. the video was of great help.

As always, your time is well spent by watching his video. Mr.Gill has ways to dust off pieces of knowledge you've forgotten & connect them like a puzzle. It's fun & interesting. You just want to know more. My great appreciation. Highly highly recommended among all test teachings.

Very Helpful, thanks

nice work!!!

gill sahab good kamm aa g

U r just excellent(best available on KZread).......it would be great help if u upload more videos for remaining part of geometry...its a deep request!

good one:)

useful information.

great job

Awsum.. really helping

Hi

By the equations of the equilateral triangle, I do not understand your value i.e Inradius= a/2sqrt(3). Because for me when I look to your drawing, let us call r the small radius, then because the line bisects the angle then we have: tan(30)=r/a/2 =2r/a this implies sqrt(3)/3=2r/a implies the inradus=sqrt(3)a/6 or?

Can you explain the simple math at about 18 min. How the area become the root3/4x a square?

Mr Gill, is it correct to assume in problem on minute 30:00 that the largest triangle is formed by two 45-45-90 triangles, in order to get DC=AD and DB=DC and calculate the area of 80 without doing so much math?

are the rest of the geometry videos available?

how could you say that angle shared by both at B (29:31) ,we can say also that angle shared by both at A write?

thanks PG made it really easy

This helps more than school

very useful video , thank you soo much

Good video

hey it was too good thank u so much.:)..plz upload more videos of geometry asap

love this

how can i see the next videos??? it is showing the private sign!!

Is it that all the triangles subtended by the diameter in the same segment are all equal.

At 32: i did not get how y = another y in that triangle?

best videos by PS

wonderful wonderful wonderful amazing amazing amazing

Hi Sir, i love your videos on youtube, and your way of making the basic concepts clear is really cool, i would love to learn Sequence and series topic from you, if you please can make a video on that topic for us Thanks

sir, u had said that the sum of the 2 side must b always >third side and the d/b the length of any two side of triangle

it's really helpful but the presentation or i better say projection of graphics was really irksome. It was not visible at many places. Hope you'd consider it.

Hello,During the time frame 6.02 you mentioned that the sum of any two sides of a triangle is always greater than the third side but previously you've mentioned that for an obtuse triangle it is ABSquare+BCSquare

@perfectscorespremium

Squaring not always result in a greater value. For example 0.5 square is 0.25. In obtuse triangle the square of greatest side is greater and in any triangle sum of any two sides is greater than the third side.

Your explanation with red pen in black background is not clearly visible. Well concepts are really amazing and helpful to me in my GRE preparation. Thankyou very much.

You are legend

Thank you !

Thanks pushpinder.. :)

sir will you please make videos on 2D geometry ,circles and quadrilaterals for gre...btw this was helpful thank you!!!!

is it useful for bank PO and ssc CGL?

I didn't understand how we derived the formula for inradius and circumradius for equilateral triangle. While I tried to solve dividing the height in 2:1 ratio, I got (a root 3)/6 for inradius and (a root 3)/3 for circumradius. Please explain to me how we got to a/(2 root 3) for inradius and a/(root 3) for circumradius. Would help me a lot. Thank you.

Hey there, at 21:30 you said that an equilateral triangle maximizes area given a perimeter. I thought a right triangle maximizes area?

@biggpete100

8 жыл бұрын

An equilateral triangle maximizes the area. That's true for all shapes.... a regular polygon (all sides equal length) will maximize the area with a given perimeter more than one with sides of different lengths. The way I like to think of it is the "more perfect" shapes hold area and volume more efficiently. BTW, a circle is the shape that has the largest area compared to its perimeter (circumference.)

sir please make some videos on mensuration and algebra............................i am preparing for ssc and arn't any as good as yours...................................n i have searched a lott.............................thanx

@ perfectScores and pushpinder gill ,please give the free access to other videos as well , I can only see this triangle video in entire geometry playlist, it would be a great help, I request you share your knownledge with us , it would be very helpful in our exams.

analogously for the circumradius, let us call R the other portion of the height, then because the line bisects the angle, we can say than Rsin(30)=sqrt(3)a/6 we know sin(30)=1/2 then R=sqrt(3)a/3

sir in 7:44 u said that any two side should be greater than the third side.suppose we add 5+2 it is greater than 2 ryt. So it may form a triangle ryt??

thnk you sir

"A particular case of the Isoperimetric Theorem tells us that among all triangles with the same perimeter, the equilateral one has the largest area. A related theorem concerning the triangles inscribed into a given circle is also true: Among all triangles inscribed in a given circle, the equilateral one has the largest area."

I am 65 years old. Is still possible to get 330+ in GRE?

good epilation

Could you explain the algebra at about 18 minutes in which you derive the formula for the area of an equilateral triangle?

For the 1st question (2 sides are 2 & 5)...you state that the sum of ANY 2 sides that are greater than the 3rd qualify as being a triangle. But yet you only chose 2 sides that were not going to be more than the 3rd. For example, for option C) 12+5=20...., but you only added 2+5. Why is that? Did you really mean to say that we should add the 2 smallest integers 1st?

@PhaNiGubbalaSSS

If you add any 2 sides they should be greater than the third....Here, he added 2 & 5 at first and the above property was not being satisfied hence the answer.
