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.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

What took you only 5 minutes took my teacher two classes to explain, thank you
you understood in 5 minutes because someone spent 2 classes trying to explain it to you
why do i always think about the hard way when there's an easy one... thanks
fintarabg sszzzz
"this is the way"
Wow I used the distance formula, took 3/4 of that, then did the distance formula for an arbitrary x,y, then solved for f(x) using the points given and then substituted for the y in the old equation and solved it to get (-3,2). Thanks, Sal.
I don’t get where he found 1:4, because his says 3:1. And on my hw it says 5:2, so should I use 1:4 as a formula??
Angel Velazques no he said 1/4 because 3 +1 is 4 so there are 4 equal parts
for simplicity's sake, multiply the change in Y and X between the two points both by the required fraction and thats your point.
k lil' bit off topic but what do you use to draw cos it looks amazing?
Can we do this without graphing? Or do we need to graph to figure it out?
Raymond Lin
go to khan academy and there is a video on how to do it. have a nice day. and God bless.
actually, I think there is one they do on youtube also
thank youuuuuuuuu very much? u save my life :)
WHERE DID YOU GET 1/4 OF THE WAY FROM
Thank you Sal, very cool!
Thank you, my teacher made this so complicated.
bruh this vid legit gave the answer to my questions within the first 7 seconds sal ur a legend
what if it's in 3 dimensional and change in x is zero
THIS IS SO HARDDD😭😭😭😭
@Sander Thao What grade level are you?
RIGHT.
what if the final coordinate doesnt end up on an intersection on the graph
Would 3/4 also have worked?
WOW! Lol. Math is the way forward!
Either he was not aware or Sal is a magician lol! He pretty much said the answer 30 seconds in! Love math!
I don’t get it..
How do you go about proving it?
Wait if it's a vetical line or horizontal line?
Using this to make a path tracing engine thanks (:
I was waiting for a catch. It's too simple.
How many segments do n points divide a given line segment? I have no idea!!
I'm confused still don't get it
How about 3/4?
Thankyou
Is there a formula for this?
1. Start at point A (1,1)
2. Move to a different location B(3,3)
3. Then in point B, turn 90 degrees to the right and move in straight line.
4. Get the first integer values (x,y) of the points C.
Exist a formula to get third point based in two points?
Thanks my teacher didn't even go through this.
What if the point is not a ratio away, it's a fixed distance?
This only help lil
Is the narrator Don Lemon?
