Geometry on Khan Academy: We are surrounded by space. And that space contains lots of things. And these things have shapes. In geometry we are concerned with the nature of these shapes, how we define them, and what they teach us about the world at large–from math to architecture to biology to astronomy (and everything in between). Learning geometry is about more than just taking your medicine (“It’s good for you!”), it’s at the core of everything that exists–including you. Having said all that, some of the specific topics we’ll cover include angles, intersecting lines, right triangles, perimeter, area, volume, circles, triangles, quadrilaterals, analytic geometry, and geometric constructions. Wow. That’s a lot. To summarize: it’s difficult to imagine any area of math that is more widely used than geometry.

  1. You math good khan tank you I am joking but really thanks a lot dude better then my mathematics teacher who cannot shut the class up and teach effectively ffs

  2. sqrt(108) = 10.3923048454 according to my calculator :p You are indeed correct in that it is a little over 6…..

  3. I’m taking my GED test on Monday……Idk how it will go but i did want to thank you because your videos have helped me with math tremendously! your voice is absolutely soothing and everything is explained perfectly ❤

  4. (teacher teaching PYTHAGOREAN THEOREM)

    Me when learning this : WHAT!! IT’S SO BASIC!!

    Me when during test : did our teacher teach this to us? I don’t know this!!

  5. I did this problem. I understand the need to factor the answer out to six square roots of 3. But I divided 108 by 2 and got 54 because when you are dealing with square root, you are essentially dividing the final answer by two to get the square. I just feel like the other method was a little too drawn out.

  6. With online learning like this it’s a wonder physical schools even exist, granted the schools are more for brainwashing then actually learning anything useful these days.

  7. I was just taking a regular shower before hitting the bed when all of a sudden the word “Phytagorean theorem” pop in my head. So I had to refresh my memory and watch this. It’s one of the weirdest thing happen to me this year.

  8. Suppose that we’ve a right angle triangle each in each quadrant of our cartesian coordinate system, and the hypotuni of each of those triangles is considered positive while our theorem here gives two possible solutions (positive and negative soln.). Why do we only take the positive solution ?

  9. I appreciate that these videos explain a concept before labeling. I learn better if I experience something and then label or categorize it.
