Tikz: Ist es möglich, diese Form mit Pfeilen zu zeichnen?

Question

Ist es möglich, diese Form mit Tikz (im Grunde drei abgewinkelte Pfeile mit einer scharfen Spitze) mithilfe von Pfeilen zu zeichnen?

Answer 1

Etwas wie das?

\documentclass[tikz,border=3mm]{standalone}

    \pgfarrowssetbackend{-.25\pgfarrowlength}%

Man könnte noch mehr Parameter einführen. Ich weiß nur nicht, was du vorhast.
