\2226
The ∦ (Not Parallel To) symbol is a mathematical operator used primarily in geometry to indicate that two lines, planes, or vectors will eventually intersect. Visually depicted as the standard parallel symbol struck through with a forward slash, it quickly conveys non-parallel spatial relationships in proofs and equations. While rarely seen in casual text or social media, it is a crucial shorthand tool for mathematicians, physicists, and engineers drafting technical documents.
