    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.
    For free. For everyone. Forever. #YouCanLearnAnything

    You saved me again Khan. I follow maths in the Netherlands, but we don't have to give reasons why, which made me very confused of the statements! I knew the statements are true, but why would you do math if you don't understand it?
    Thanks!

    could you split quadrilateral AEDF into two triangles and find congruent by SAS, since AD = AD using the "reflective property" and find same answer that way?

    can you say it is CPCTC?

    • @adityasaha6508
      @adityasaha6508 6 ปีที่แล้ว

      the regents no longer accepts CPCTC as a justification

    I made an extremely convoluted proof to solve the first problem, but it accidentally also solved the second problem lol. Essentially I made a line segment AD, and showed the triangle CAD and BAD were congruent. Therefore BD is congruent to CD. Using this and the fact that the angles FDC and EDB are congruent that meant the triangles FCD and EBD were congruent. Meaning ED is congruent to FD (Second problem), and if CD is congruent to BD and DF is congruent to DE that means since point D sits on the line between BF and CE that BF and CE are congruent. This stupid proof somehow solves both problems in probably the worst way possible
