Two lines are said to be coplanar if they have the same plane. This means that they intersect at a single point, and their distance from the point of intersection is constant.
Imagine two lines drawn on a plane, one above the other. These lines are coplanar if they intersect at a single point. Conversely, lines that are not coplanar will intersect at different points.
Examples:
Collinear lines: Two lines that are not coplanar will never intersect.
Parallel lines: Two lines that are parallel and not intersecting are coplanar.
Non-parallel lines: Two lines that are not parallel and intersect are coplanar.
Further insights:
The distance from a point P to a line L is called the distance from P to L.
The distance from a point P to a point Q on line L is equal to the distance from P to Q.
The angle between two lines is the angle formed by the rays of the two lines.
Two lines are coplanar if and only if the angle between them is equal to 90 degrees
