Derivation or Proof of Heron's formula : Find area of a triangle with given sides | Logic Behind

Heron's formula is very useful to calculate the area of a triangle whose sides are given. This video is for all of you who come to my channel to find proofs of formulae.

[@ScottESchmidt]

Years of geometry, trig, algebra, calculus, diff eqns, and linear algebra, and I guess I never learned Heron's formula! How ever did I miss this? Very handy, especially in things like surveying where the triangles are usually not right triangles, the side lengths are the easiest measurements to make, and area is often the item of interest.

[@tamirerez2547]

The proof is nice and neat, your voice is clear and pleasant, it's just a shame that you can't read the sloppy handwriting.
The letters are getting smaller and smaller, the dividing line is crooked, the brackets are crooked, unpleasant to watch.
A math teacher must write in clean and clear letters.
It could be an excellent channel, but the terrible handwriting spoils everything.
Anyway, big LIKE👍❤️ to the effort and the nice proof. With hope that you will improve your handwriting.

Mam I have a doubt that the Pythagorean theorem is H2= P2+B2 so how you can write in triangle ABD as H2=c2 - d2

When h² = b²+p² , how did you write h² = c² - d² ?

In first h² 'h' is Hypotenuse of triangle and in second 'h' it is height of triangle

I also want to know

[@pranavmundhra4519]

It's the semi perimeter , means that the perimeter of the triangle divided by 2

[@chetanpundir5730]

Its just an assumption to ease the calculation, you can avoid taking s
But you will end up lengthy formula.... Chill bro

Because no one cares about proof until its given in book😂😂
That's reality

[@mrjnutube]

All of a sudden, you introduced "s=(a+b+c)/2". How and why?

[@thezen9]

This could have done with a better explanation, but I'm almost certain it comes from knowing the final solution.
if you were to go through the process without s and just use (a+b+c)/2 instead you would realize the recurring value and likely assign it to a variable such as s to make it easier to read.

[@josephmalone253]

s is the semiperimeter which is the perimeter a+b+c divided by 2. It is the perimeter divided by 2.

[@thezen9]

@@josephmalone253 The question was not of what it is, but how they knew how to define it.

[@josephmalone253]

@@thezen9 how did they know how to define it?

[@thezen9]

​@@josephmalone253 In the video it's likely because it had been solved long beforehand and they likely had a proof for it on hand.
Originally it was likely first simplified without s, and the repetition of (a+b+c)/2 was noticed and then s was defined as this value to make it cleaner and more readable/useable.

[@seetharamulugampala5815]

Derivation means we should not use terms of herons formula like s=a+b+c÷2 in the middle of derivation

[@jonsnowprogaming6291]

(a+b+c)/2 can be taken as an unknown s. This is incorporated into the formula
