Geometric Mean Example problem similar triangle
In this is yet another example of geometric mean with similar triangles where a right triangle with an altitude is split into three similar triangles. Thanks to math site I used with the applet that shows the translations to create the three similar triangles.

Doesn't it suck that so many students are coming online to get math help because our teachers/curriculum/school system is incompetent

I don't think it shows incompetence. I see this as a tool that is helping students understand mathematics better than any generation of humans before. The students under the age of 20 should be some of the best mathematicians of all time. Imagine what could have happened if Ramanujan had youtube when he lived in India. I think it opens up access to high levels of math for students around the world..... It is awesome, and I hope to live to see some of the fruits of this labor. Thanks for the comment.

I completely agree with all you've said! The internet (specifically places like KZread) are amazing resources for students, and I think it's great that we are lucky enough to have such things available to us. The point that I was trying to make was that it's a little sad to see so many people commenting that they weren't taught the concept(s) in a way they could understand in the first place. I realize now that my first statement was a bit general; sorry if there was confusion. But know I truly appreciate videos like this, thank you for posting them.

They changed the curriculum to supposedly help the kids, but nobody is better. The teachers are worst, and the kids are dumber
I've spent the last 4 days sitting in geometry class with no idea what the hell my teacher was talking about... watch a 10 minute video and I understand it completely.

@Bryan Hernandez a job wont necessarily have you find geometric mean. But I am a big believer that forcing your brain to work through this and learning the math terminology that allows you communicate your ideas to other humans is what is important. The only education that is important is what you teach yourself. Forced education doesn't work. Although learning more math never hurt anyone. And skipping school does.
You're a better teacher than my geometry teacher is. You taught in 10 minutes what it takes her to half-teach in about 35 minutes.

God bless this video!!! My geometry teacher taught us a totally different (hard/confusing) way, but this way is (1000000x) easier!! Thank you sooooo much for doing this!
I watched every video on geometric mean and i didnt understand it understand until i watched this one
Made me learn and understand in 10 minutes what my actual teacher couldn't teach me in 2 hours. What an absolute chad
my teacher has me confused, but you are getting me into this more, thank you. really.
THIS HELPED SO MUCH! Please make more videos like this, you explain everything SO WELL!! :))
After 15 videos this is the only one that made me understand THANK YOU
Woah you enlightened me... I didn't get it until I saw the triangles separated like that... Thanks a lot
Thank you so much for this video!! I might actually get an a on my geometry test tomorrow!!
JESUS! THANK YOU FOR THIS VIDEO! everything makes sense now!! it all clicked in a matter of minutes into the video! compared to an hour lesson in class! you make my geometry teacher look bad! probably bc he is. THANK YOU
Got more useful information from this than my actual teacher so if u see this sir thank you so much
This video just helped me understand the hardest area in geometry for me.
Thank god for a decent explanation of geometric means.

Great vid, thanks for the help!
you can also solve it using euclid’s second theorem, because it says that a square built on the height relative to the hypotenuse is equal to a rectangle that has for sides the projection of the 2 sides on the hypotenuse, so you find x immediately by building the rectangle and extracting the square root, then you just do pythagorean theorem and you’re fine
Thank you so much!!! i'm not going to fail my first test! :D
Your legit a life saver that you so much!!!
Thanks so much. I have a test in a few days and I did not understand this. But now I do, thanks so much
Thnx ur teaching style is the best and super
When you learn the concept in 9 before 10 minutes from your test
Thank you. Now imma past my math exam tmw
Took my teacher 30 min to explain and I didn’t understand After watch this video I completely understand
Thanks! Helped a lot!
thanks broski, passing my test tomorrow
im just glad we can zoom up the lesson unlike in real life
You helped me more than my Teacher.

thank you for simplifying the answer but I think there is a better method than the one which you gave you can say: x^2=12×5 then you will get the answer
When you find the height of the triangle, then you can calculate the area of that triangle. Please go forward and use Heron's farmula to recheck that all calculations are up to the mark. This has to be done at 8th standard world over. -
My question is: (at 0:58-1:02) why has the smallest triangle taken out that way? Basically what is the concept behind interchanging the sides 'r' & 'H' ?
Did I just learn more in 10 minutes than I did in 14 hours of school

Mon Bon look up videos on how to simplify radicals. Here when you factor out 60 to its prime factors 5 and 3 are factors that do not make a perfect square.... so 15 stays in the radical.

What I like to do is look at the triangle. Most in your textbooks are drawn to scale. Is the largest angle across from the largest side? In this video we are dealing with right triangles. You could use Pythagorean theorem to check you answer. I don't think I have had that question. Sorry it took 3 days to answer. But that is what I do. I mainly use triangle inequality theorem to check and the fact that I have literally solved thousands of triangles:)
I never understood how to do this until now

How do we know that the triangles are similar? Is it stated in the problem?

Angle angle similarly. I didn't go through the proof. There is a right angle and each of the triangles share the bottom left angle. I thought about putting that in there, but try to keep my bids under 12 minutes
how do you get 2 radical 15
@knowyourhorse
6 жыл бұрын
so radical 60 has factors of 4 and 15. four is a perfect square with a square root of 2. 15 is not a perfect square and contains no perfect squares. . . so your final answer is 2squareroot(15)
