Coplanar refers to points, lines, or shapes that exist within the same geometric plane.

Examples

The points A, B, and C are coplanar if they lie on the same flat surface.
In a 3D space, two lines can be coplanar if they intersect or are parallel.
Understanding coplanar points is crucial for solving problems in vector geometry.

Meaning

In geometry, when two or more objects share the same plane, they are considered coplanar. This means that if a straight line can be drawn to connect any two points within these objects, the entire set remains on this single flat surface.
