## mathslover 3 years ago Hi guys please have a look to my power point presentation of Heron's formula ...

1. mathslover

here it is

2. mathslover

i trust on you all so please :

3. mathslover

macro commands? it includes some images no commands

4. jiteshmeghwal9

@mathslover i can't open this file becoz it's gonna saving & this will make me lost my MB's & my bro has specially said nt to save any file :(

5. mathslover

it is of 2 MB dude

6. panlac01

lol

7. uri

Hey what is this? @mathslover there is some file saving? xDD

8. mathslover

@uri and to all students viewing this: it is just of 2 MB and i have made this .. please have a look to that

9. uri

Okaay :)

10. panlac01

he's saving the very bit he has left.

11. waterineyes

12. mathslover

hmn it seems that your net is too slow no problem @waterineyes please see it ..

13. uri

14. hartnn

Quite appreciative work, @mathslover .Are u a teacher? You proof read it for typos?coz i found one....

15. panlac01

you can use .docx or .doc so the file is smaller, mathslover

16. waterineyes

Yeah I am using Internet Stick..

17. mathslover

May be that there are some typos if there are then sorry

18. waterineyes

2 minutes remaining.. Net is not too slow I think..

19. waterineyes

40 seconds remaining..

20. panlac01

took me literally a split sec to dl it

21. jiteshmeghwal9

well i downloaded it @ the end too good :) @mathslover :)

22. mathslover

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

23. panlac01

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

24. mathslover

thanks panlac01

25. waterineyes

It looks good to me..

26. mathslover

thanks @waterineyes @mukushla

27. uri

Oh! i got it @mathslover :D

28. waterineyes

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

29. mathslover

30. waterineyes

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

31. mathslover

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

32. waterineyes

Welcome dear..

33. mathslover

wooh not a big diff. but yes thanks

34. AravindG

vry nice @mathslover

35. mathslover

thanks @AravindG

36. AravindG

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

37. ParthKohli

Of course, 1/2 b h.

38. AravindG

so both formula can be used for any triangle??

39. waterineyes

But if you know what height and base are ..

40. ParthKohli

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

41. panlac01

without knowing the height

42. ParthKohli

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

43. AravindG

i seee

44. waterineyes

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..

45. ParthKohli

Yep, that is what I mentioned.

46. mathslover

well waterineyes is right it depends on condition

47. waterineyes

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

48. mathslover

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

49. uri

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

50. waterineyes

Yeah You once gave the tutorial I remembered @mathslover

51. mathslover

@vishweshshrimali5

52. 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

53. panlac01

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 - http://jwilson.coe.uga.edu/EMT668/EMAT6680.2000/Umberger/MATH7200/HeronFormulaProject/finalproject.html#anchor1209606

54. mathslover

*his @panlac01 i am male

55. uri

Her? :P

56. panlac01

57. uri

Lol don't expect much @panlac01

58. vishweshshrimali5

Very nice work @mathslover I appreciate your efforts........

59. panlac01

next I am going to call everyone an IT...

60. mathslover

:D .. thanks @vishweshshrimali5

61. vishweshshrimali5

the best way

62. jiteshmeghwal9

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

63. mathslover

yes

64. jiteshmeghwal9

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

65. 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

66. jiteshmeghwal9

k!

67. jiteshmeghwal9

yes! thanx for clearing my doubt :)

68. mathslover

69. mathslover

@apoorvk

70. Vaidehi09

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

71. mukushla

$\huge \text{Nice}$

72. mathslover

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

73. precal

aka Hero's formula (I read that somewhere)

74. sauravshakya

good job

75. mathslover

thanks a lot @sauravshakya

76. navpreet

Really good. =D

77. ajprincess

Gud work. @mathslover

78. mathslover

thanks @navpreet and @ajprincess
