    This is aproximate method, since those two arcs (initial one and arc of 180 degrees) are NOT congruent. You are not supposed to prove solution by using marked protractor. Simple solution for trisecting of 90 degrees angle is already well known and you don't need to draw aditional 180 degrees angle/arc. Just use the same radius AE, mark 60 degrees from point E, then repeat the same from point D. Also, try your "method" for randomly chosen angle, i.e. 64 degrees and 2 minutes and prove that 3 parts are really equal using only compass. Thanks for reading.

    Try drawing 20⁰ by trisecting that 60⁰. You can't trisect every angle with only straight edge and compass.

      yes. your are right. but we can trisect 30°,60°,90°, . . .

    "angle trisection" was proved to be impossible in 1837 by Pierre Wantzel.

  • @SebastianGMSFB

    Judging by how factorial-numbers often have a consistent ratio of prime-factors between the powers of 2, 3, and 5, I consider Trisection to be:
    •Twice as important as dividing an angle by 5... But also:
    •Half as important as Bisecting an entire circle.
    So 720 (being the 6th factorial-number, 6!) is my favorite number to use when subdividing a circle by multiple parts/pieces, and guess what: This is *almost* the official way to subdivide a circle, only that a Circle is actually normally divided by 360 degrees, which is exactly half the number 720... Very close-enough to satisfy my preference upon how I would prefer to split a circle by! 🙂

    @francistorchio 2 роки тому +3

    One of the classical problems of Greek mathematics along with squaring the circle and duplication of the cube. None of these problems have been solved using only a straight edge and compass. When we want to trisect and angle it means all angles and not just 90 degrees.

    Please correct the title and description of the video.
    It works only for 90 degree, however it is a rather complicated way to obtain 30 degree.
    Anyway, your title suggest that you provide a method which works for every angles. But this is not the case.
    You mislead many people who try to apply your method.
    Anyway, the trisection of angles is an old classical problem, with many surprising results and connections with different branches of maths, see e.g. en.wikipedia.org/wiki/Angle_trisection (the hungarian version is more compact: hu.wikipedia.org/wiki/Sz%C3%B6gharmadol%C3%A1s )
