This question doesn't state where or why a triangular screwdriver is needed, so this may just be a "wind-up" or "troll" question.
It is is very unusual to need a screwdriver with a triangular-shaped tip!
Anyway here's how it may be possible to do it:
Grind the tip of a normal screwdriver to a point using a suitable power grinder.
Then place the shaft along a suitable heavy piece of steel - such as an off-cut of railroad rail placed upon a solid floor or a very strong workbench, or similar - and try to flatten the shaft of the screwdriver to get a triangular cross-section (with 3 long edges) by using a suitable heavy hammer.
If the shaft doesn't "take" the hammering you will first have to anneal the shaft of the screwdriver by heating it up to red heat and then let it cool in the air slowly. To be sure it gets the best chance of annealing fully, don't "quench" it by using water or an air line to try and cool it down more quickly.
Then try hammering it to the triangular shape you want. If will be very tricky to do because as soon as you hammer the opposite side to the "sharp" side of the triangular cross-section, you will find you flatten-out the sharp side! One way to avoid that happening would be to machine a V-shaped groove of suitable depth into a a piece of steel and then hammer the shaft into the groove. But, to be able make that groove, you would need to know how to use the right kind of machinery - such as a shaping machine or a milling machine - and, if you already had that kind of machinery available to you, you would not be asking this question here!
After you have hammered the shaft into a triangular cross-section - assuming you find you really can do it! - you must then harden the shaft again by heating it up to red heat and then quench it as quickly as possible by plunging it into a large bucket of cold water.
If you don't harden it properly before you try to use it as a screwdriver, the shaft will just twist around and around because it is too soft!
Good luck!
