Euclid as the father of geometry, Introduction to Euclidean geometry, Geometry, Khan Academy

We don t normally delve too far into history when talking about math, but sometimes it s important to have perspective about how some of our math concepts came about and how influential they have become. Watch the next lesson: 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 largefrom 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 existsincluding you. Having said all that, some of the specific topics we ll cover include angles, intersecting lines, right triangle
