From "De la Terre à la Lune":
Là, sur de vastes plaines, on devait établir d'immenses figures géométriques, dessinées au moyen de réflecteurs lumineux, entre autres le carré de l'hypoténuse, vulgairement appelé le «Pont aux ânes» par les Français.
However, according to Wikipedia:
Pons asinorum (Latin for "bridge of asses") is the name given to Euclid's fifth proposition in Book 1 of his Elements of geometry, also known as the theorem on isosceles triangles. It states that the angles opposite the equal sides of an isosceles triangle are equal.
So Verne seems to have mixed up two different theorems.
