L'invention concerne un pantographe à angle universel pouvant produire aisément et exactement n'importe quel angle et la moitié de l'angle. Un parallélogramme à quatre côtés de longueur égale est formé de deux premières règles (120) et de deux secondes règles (130). Une règle de référence (110) est placée sur la diagonale du parallélogramme. Les parties des premières et secondes règles (120, 130), placées aux sommets opposés du parallélogramme, sont soutenues coulissantes et de manière fixe le long d'une rainure de guidage (111) de la règle de référence (110). L'angle formé par n'importe laquelle des deux premières et secondes règles (120, 130) et la règle de référence est l'angle à obtenir.
