, de Descartes et de Gauss Théorème de Wantzel Abel Un nombre constructible est donc est constructible ! Conséquence 1 : la duplication du cube est impossible : Selon le théorème de Wantzel, n'est pas constructible et par suite et la duplication du cube est impossible Q et non constructible. Conséquence 2 : la quadrature du cercle est impossible : quadrature p est transcendant Lindemann p . Il faut donc construire p Quadrature approchée du cercle selon Dinostrate Conséquence 3 : la trisection de l'angle est impossible : trisection de l'angle x : par projection, cos x = OH et la formule : x - 3cos x montre que cos Il est clair que les angles de 180° et 90° sont trisectables ; d'ailleurs si x est trisectable, son double (par report) et sa moitié (bisection) le sont aussi. Ainsi 45° est trisectable : trisecter 90° : on obtient 30°; bissecter 30° : on obtient 15°. Q p Or, il est facile de prouver ci-dessous Gauss Noter que les mathématiciens arabes avaient déjà soupçonné l'impossibilité de la trisection géométrique de l'angle en ramenant le problème, comme le fit ultérieurement Al-Biruni : N = b /2. Donc b est pair. Posons b = 2c. Il vient a
