    I'm really not sure where you're getting these postulates. These are ones that I find:
    1. A straight line segment can be drawn joining any two points-this postulate asserts that space is connected, and nothing will prevent straight lines form connecting two points.
    2. Any straight line segment can be extended indefinitely to form a line-this postulate says that space is infinite.
    3. Given any straight line segment, a circle can be drawn having the segment as radius and one endpoint as center-this postulate asserts the existence of circles, and describes their form.
    4. All right angles are congruent-this postulate asserts that all right angles are the same and forms the basis for the exploration of all sorts of angles as well as parallel lines in the propositions.
    5. If two lines are drawn which intersect a third in such a way that the sum of the inner angles on one side is less than two right angles then the two lines inevitably must intersect each other on that side if extended far enough.

    Clear, detailed instruction, Thanks
    I linked to your video in my video description.

    dude the 3 points and the plane is a consequence of postulate 1 so why you say postulate 2 remove or change this video

    is this about unlimited detail?

    The outstanding mistake and appears 2,000 years ago with a point which can not be measured. It appears in almost all geometries.
    No one has ever seen a point, we just draw pictures of them. This is Gauss' Gordian Knot (space).

    I guarantee the line I visualized through the two points was different from other people's. My line was a fuchsia color.

    First thing you should say: Something is very clear that we know without proof. How do you know for me everything is very clear for me. Why should I accepted this postula without proof? :)

    Furthermore; as Einstein made; if I deny the postulate of euclid, how should I know; what is triangle....:)

    6:49 did you mean to say one line?

    thanks I'm in 9th grade and my geometry teacher sucks so this will help me on my test tomorro

    I dont understand the purpose of this video. I understand the things being discussed slow as it was but I dont get the point of it all pardon the pun.
