A file that is triangular in cross-section.
No such thing A tetrahedron is a polyhedron composed of four triangular faces, three of which meet at each vertex. Similar to a pyramid but with a triangular base.
The most common use of a triangular file in a chemistry laboratory is to score (scratch) and weaken small diameter glass tubing prior to breaking it. This makes the glass a) easier to break and b) more likely to break cleanly where the score is instead of randomly, leaving jagged edges. Pressure is applied on the OPPOSITE side of the score; remember to protect your hands with heavy gloves and/or a thick cloth.Large diameter tubing requires different methods; the "score and snap" technique tends not to work so well.
Four - as a square has four sides, there are then four triangular sides (meeting at the top of the pyramid).
Triangular structures are more stable than rectangular structures because the triangular shape distributes forces more evenly, preventing the accumulation of stress at specific points. This design also allows for better weight distribution and resistance to deformation, making triangular structures more rigid and stable overall.

Atriangular file is a hand tool used for removing material from the surface of a job. It has a triangular cross section. The cross sectional area and length are designed to the ISO standard. Like other types of files triangular files can have various tooth cuts, smooth, medium and hard.
A triangular file is often used to stir chemicals, as well as to scratch glass tubing before breaking it.

A three-square file, also known as a triangular file, is a type of hand file used primarily in metalworking and woodworking for shaping and smoothing edges, corners, and surfaces. Its triangular cross-section allows it to reach into tight spaces and create sharp corners or grooves. It is commonly used for filing notches, keyways, and other detailed work where precision is required. The three-square file can create a flat surface on one edge while maintaining a pointed end for intricate shaping tasks.
It is a flat file (as opposed to round, oval, square, or triangular), with rather medium cross-cuts. It is used for filing common materials such as wood or metal.
