Coplanar Lines. Coplanar Lines are lines which lie on the same plane. Two parallel lines or two intersecting lines always lie in a plane. Thus, two line are coplanar, if and only if they are either parallel or intersecting. Lines in three dimensional space are coplanar, only if they are not skewed lines. Two lines which are neither parallel nor intersecting are called skewed lines.
This is easily visible when the equations for parallel lines are listed in slope-intercept form. If the slope variable is the same, the lines are parallel. Here are a few important things to remember: First, every line can have multiple parallels. A line will be parallel with any line which has the same slope, so many lines can be parallel at once. Second, line segments might not be parallel even if
