4:51 - at perpendicular conjunctions of two straight lines, only ONE 90 degree symbol is needed. The other side is automatically 90 degree based on 90+90=180: succinctness is the essence and beauty of math at least for this level (enjoyed this series!).
The instruction is very well laid out, but it would be nice for you to use real numbers, as opposed to the square root of a number. I'm teaching math to a group of fabricators and I've done so with machinist, but the hypothetical numbers that are used in these examples are never applied in real-world environments. Angles aren't theta and sides aren't the square root of a number. Most of my students have had the misfortune of learning math in high school with this same logic, leaving them completely unaware of how to use it in the real world.
lol at people quoting formulae. This is practice for logically breaking down problems, a skill you will need when formulae become inconvenient/nonexistent.
If you're confused about the square roots numberings the adjacent side (small side)=x hypotenuse (large side)=2x opposite side (medium side)=X times the square root of 3
III • it’s always 6 equilateral triangles so you can just use the equilateral triangle area formula and then multiply by 6 bc there are 6 little triangles in the hexagon
isnt it sad that I can get a better education off of youtube than in my high school math class! Thanks!
Are you paying attention?

I really love how maths can prove itself no matter what problem is involved. Great video :)
A formula I came up with is when side length is SL you can then take 3SL* (SL/2)*sqrt3. It will always work.
Thx you helped with my homework when I watched your vids I'm in a 3rd grade class G.A.P class in Mr. Gordon
Woah you’re in 7th grade now, right?
You are in 8th now!

Thanks for the info!
people who need only the apothem go to 3:00
thanks
Thx bro
saved my life.
The area of a regular hexagon is: (perimeter)(apothem)*1/2, where the apothem is the altitude of equilateral triangle.

We could have also used Heron's Formula to find the a area of a single triangle.
Anybody here in 2021?
You help so much
Thank you so much.

Thanks you helped me alot with my homework
I love how he is just like, "AND WERE DONE!" at the end. he might have not liked this lesson...
Very good.
Great video who agrees
area of equal triangle= X^2*sqrt3 /4
If you're confused about the square roots numberings the
adjacent side (small side)=x
hypotenuse (large side)=2x
opposite side (medium side)=X times the square root of 3
Thanks
hi, can you please remake the videos of calculus, and give some new examples.
What program did you use to make the marks in this video?
@khanacademy shouldn't it be multiplied by 12 since the right triangle is half the equilateral triangle
area of a hexagon 1.5*X^2*sqrt3
X=side
area of hexagon is 3.√3/2.a²
thnxs
tht 3 concept u wrng u took the wrong side of it ,u have to take the side opposite ti the right angle nt the side whr the right angle is present
Cant we just use the formula for equalateral triangle instead????.that way we don't have to figure out the
height
the long cut of finding the area shouldve use formula area= 1/2apothem*perimeter; with apothem= s/2*sqrt3. less chances for error.
What does he mean by "Two squareds of 3". How what does that equation mean and how can I read it?
Is 2√3 = 3.4641016151377545870548926830117
if i know one side do i do that number multiplied by six?
I don't know why you can't prove it generally. Why you have taken side length = 2√3
No 2kbling, he found the area of 1 triangle then multiplied by 6. Your referring to HALF A TRIANGLE!
Nope. He changed it later..and found the area of the whole triangle.
how do u get 2sqrt3 there
the side of the hexagon is assumed 2sqrt3
I still don't understand it
III • it’s always 6 equilateral triangles so you can just use the equilateral triangle area formula and then multiply by 6 bc there are 6 little triangles in the hexagon
7:51
with 5 areas out of six, of six pointed star are given, how to find out the sixth area of the triangle with thoose given 5 areas ?
anyone pls help me.
I'm, what happened to splitting the hexagon into 2 trapezoids?...
1st! wooohoooo
Nice
How come the apothem is 3?? 😅😅
IDK if its just sleep deprivation but I'm still confused
Cyblohexane
this doesn't apply on every no. like try on 6cm of each side of hexagon...
try this-3√3 a^2/2
We're learning about this and I'm in 7th grade 😩 I'm not even in honors or accelerated
I use Khan academy
I'm in grade 10 and I find this very difficult and confusing.

Thoda hindi vaalo ka bhi dhyaan rakh lete angrej
why is the 2Sq of 3 .. I'm trying to learn.. I don't know it that's the actual length, if so use a normal ###### number... of it it's a formula..
what is an altitude?
height of the triangle basically. he created a line from the vertex of the hexagon to the base of one triangle and called that line the altitude.
Thank you!!
