    Thank you so much, I hate math and it makes me so unmotivated to pay attention to it. This made me understand it so much since I can never understand what my teacher says (he has an accent). Thanks so much, omg!

    Great! Really polished my crap understanding of medians and centroids, and really triangles.

    A big jump! 5:36 - The applicability of median rules of 2D triangles to 3D triangles here should be proven 1st before being used as done here.

    how did you get 4c squared/ 36?

    • @firethylacine1976
      @firethylacine1976 7 лет назад +2

      Rose B He originally had c squared/9 (c/3-0, he then squared). In order to get a common denominator he multiplied the numerator and the denominator by 4.

  • @jritzeku

    Why is only the denominator square rooted? For instance, why is square root of a^2/9 = a^2/3? Shouldn't it = a/3? square rooting both numerator and denominator.

      @godofgamers3884 6 лет назад +4

  • @lennybiller1666
    @lennybiller1666 10 месяцев назад

    why do you square root a^2 over 9, b^2 over 9, and c^2 over 9?

  • @mileallen972
    @mileallen972 8 лет назад

    So a segment of a median can be 1/2 or 1/3

    My teacher send a link to this video but I need the answers for the assignments he has so reply to this comment for me to send a link to the work so you can give me the answees

    when u went on about that triangle with extending lines i had no idea what u were talking about ppl don’t learn that before centroid so u shouldn’t b using advanced stuff with a basic problem

    • @lillythegoddessreadbio3552
      @lillythegoddessreadbio3552 6 лет назад +3

      Or ....you should have payed more attention in class...I'm here to learn what I haven't picked up yet...but u definitely learned this in class if ur looking it up....next time...pay attention
