We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.įor free. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We tackle math, science, computer programming, history, art history, economics, and more. To summarize: it's difficult to imagine any area of math that is more widely used than geometry.Ībout 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. 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.

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. If a radius bisects a chord, it is always. 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). This geometry video tutorial provides a basic introduction into circles as relates to chords, the radius of a circle as well as its diameter.
