Quote:In geometry, a set of points in space is coplanar if all the points lie in the same geometric plane. For example, three distinct points are always coplanar; but a fourth point or more added in space can exist in another plane, or, incoplanarly.

yes, 3 points are always coplanar. however, in the example you gave the lines (though they aren't technically lines) do not remain in the same plane. they curve outside the plane of the three points. because the lines curve they are not line segments, and because they curve outside the plane of the 3 points they are not coplanar either.
I do not feel obliged to believe that the same God who has endowed us with senses, reason, and intellect has intended us to forgo their use and by some other means to give us knowledge which we can attain by them.
