thanks a lot @jiteshmeghwal9
any suggestions?
@panlac01 how was it?

- anonymous

I skimmed through it. and it looks a lot better than most of the documents I've seen.

- mathslover

thanks panlac01

- anonymous

It looks good to me..

- mathslover

thanks @waterineyes
@mukushla

- uri

Oh! i got it @mathslover :D

- anonymous

But there is mistake also.
Hope you will correct that..

- mathslover

yes .. please tell

- anonymous

Example 2 has all the units in meters..
but you have found area in cm^2..
Be careful..
84 m^2 will come there..

- mathslover

oh yes units matters a lot ... i will correct it now thanks a lot waterineyes

- anonymous

Welcome dear..

- mathslover

wooh not a big diff. but yes thanks

- AravindG

vry nice @mathslover

- mathslover

thanks @AravindG

- AravindG

one doubt:which is more general "heron's formulka" or 1/2bh?

- ParthKohli

Of course, 1/2 b h.

- AravindG

so both formula can be used for any triangle??

- anonymous

But if you know what height and base are ..

- ParthKohli

Yes, but I do prefer using Heron's if you know the side lengths.

- anonymous

without knowing the height

- ParthKohli

Finding the base and height is tedious in some cases, so...

- AravindG

i seee

- anonymous

It depends upon conditions..
if you are given with height and base then 1/2 bh
If you are given with sides lengths then Heron's Formula..

- ParthKohli

Yep, that is what I mentioned.

- mathslover

well waterineyes is right it depends on condition

- anonymous

I am just mentioning what you mentioned..
Ha ha ha..
Afterall you are faster than me..

- mathslover

For a perfect tutorial you may go here:http://openstudy.com/study#/updates/50040ea5e4b0fb991133649e

@ParthKohli why don't you do something like that? :P

- anonymous

Yeah You once gave the tutorial I remembered @mathslover

Hey guys i want to mention one thing : there are 2-3 errors in the ppt, please neglect them ..
I will post the correct ppt later. .. sorry for that

- anonymous

I was complimenting mathslover how her demonstration came close to still images. must've been tedious drawing all those
Salman Khan has a good video demo on this one also. http://www.khanacademy.org/math/geometry/triangles/v/part-1-of-proof-of-heron-s-formula
but this has the most work -

the best way

i have a doubt @mathslover is this formula for every type of triangles ?

- mathslover

yes

- jiteshmeghwal9

then why there are other formulas to find the areas of equilateral triangles etc. ?

- mathslover

they are to make the process easy :
see the ppt again i had proved the formula for finding the area of an equi. triangle by using heron's formula

- jiteshmeghwal9

k!

- jiteshmeghwal9

yes! thanx for clearing my doubt :)

- mathslover

your welcome

- mathslover

@apoorvk

- anonymous

great job @mathslover! i wonder how much time u invested in making that!
there were just some minor typing errors, but all-in-all, it was a great effort.
and wow...that was one BIG formula to find the area of quadrilateral using Heron's! :D

- anonymous

\[\huge \text{Nice}\]

:D thanks @Vaidehi09 well it is hobby to make such ppts for the welfare of students :)
