👉 The term "non-planar" refers to a shape or configuration that is not planar. A plane is a flat surface that extends infinitely in all directions, while a non-planar shape does not have this property. Examples of non-planar shapes include: - Non-circular: A circle is considered non-planar because it has no curved side. - Convex: A convex polygon is also non-planar, as it has no straight sides that can be bent into any other shape.
