trigonométrie antique ?

Bonjour à tous,

"Les Mésopotamiens, as de la trigonométrie ?"

Ce n'est pas celtique, mais cela n'aurait-il pas pu l'être?

"Au lieu de déduire la longueur d’un côté du triangle rectangle en fonction d’un angle et d’un côté, les Babyloniens auraient ainsi utilisé le rapport de deux côtés d’un triangle rectangle pour déduire le troisième. Un tel usage pouvait être mobilisé par les architectes, dans les calculs préalables à la construction de pyramides à degrés (appelées « ziggourats » dans le monde mésopotamien), de canaux, etc."
