    Very clearly presented. The INCENTER is a WIN CENTER.

    It's explained in the video. The angle bisector line is, at all times, equidistant from the two adjacent sides that form the angle. The instructor eyeballed it for the video, of course, but that's how he was able to draw them reasonably accurately.

    when u draw the angle bisector how do u no where 2 draw the line inside the triangle?

    • @iamdannyel3285

      The line from the incenter to the side must be perpendicular to the side

    Is the incenter ( point I) the same point as the center point of the circumscribed circle around the given triangle ABC? What if ABC triangle is equilateral- is the incenter( point I), the same as the center of triangle ABC’s circumscribed circle? What is the ratio of the circumcircles radius to the in circles radius?

      For an equilateral triangle, the circumcentre, incentre and centroid all coincide.

    isn't that an orthocenter?

      19.6.55- no

    • @dhruvpant7926
      @dhruvpant7926 6 лет назад

      19.6.55- orthocenter is intersection of perpendicular dropped on three sides from the opposite vertex

    You are saying that IF and IE is equal!! how??

    • @IbrahimAhmed-nr4lb
      @IbrahimAhmed-nr4lb 7 лет назад

      Because incenter is equidistant from all the sides of the triangle and IF and IE both come from a side of the triangle

      Shubhan Kumar when did he say that? That’s definitely not true
