No; it simply means they are all on the same plane, as are two-dimensional figures.
parallel, especially if only talking about planar (two dimensional or flat) geometry
What is two-dimensional
Straight lines.
two-dimensionalOn a+ the answer is three-dimensional
Lines! Yes, they are one-dimensional. Points are zero dimensional, planes are two-dimensional, and prisms and such are three dimensional.
Parallel lines are two 1-dimensional objects that do not meet. Parallel planes are two 2-dimensional objects that do not meet.
A two dimensional plane.
Think of the strings as writing on lines of paper. Paper is a two dimensional surface. The computer array is the equivalent of the two dimensional paper.
As many or as few as you like.
In that case, it wouldn't be called a "line".From superscot85: No, all lines are one-dimensional, just as all points are zero-dimensional.
Not necessarily.
Never! Coplanar means that the two lines lie in the same two-dimensional plane. The only way that two lines do not intersect in two-dimensional space is if they are parallel. And by definition, skew lines are not allowed to be parallel, either.So essentially there is no such thing as skew lines that only occupy two dimensions. Skew lines must be in three dimensions or higher in order to (1) not intersect and (2) not be parallel with each other.
For two dimensional lines: Get the formulas for the two lines into a format so that you can evaluate the slope. If the slopes are different, then they will intersect. If the slopes are the same, then you have two parallel lines, or possibly, the two equations describe the same line.
There are two two-dimensional figure with an infinite length. They are rays, and lines.
no, if two lines are not parallel then the will eventually have to intersect.Alternate perspective:Yes, if two lines are non-parallel, they need not intersect in three dimensional space.
Normally, yes. A transversal contemplates crossing two (normally parallel) lines in conversations about two dimensional space and the relationship of certain angles. If you are talking about three dimensions, all bets are off. Two skewed lines in three dimensional space could would have a line that connects them but none of them would be coplanar.
