Can someone double check my hw? I am redoing it and I just want to make sure I have it right. It's saying if posulates are true sometimes true or never true.

    "2 planes contain the same point" : sometimes, it is true. Logic: if 2 planes intersect, their intersection is a line and the line has many points. All points belongs to both planes --> 2 planes contain the same point is correct.

    Four points lie on the same plane: sometimes, it is false --> green.

    Oh I thought in order to have a plane you had to have three points

    when they say "a plane contains a 3 points" they meant the plane has exactly 3 points, no more. You are correct when saying 3 points form a plane but it doesn't mean that plain contains just those 3 points.

    a line and a plane intersect at exactly 1 point: green it is always true if the line is not on the plane it is sometimes true if the line is on the plane. In this case, it is not "exactly 1 point" but "infinite many points" Hence it is green
