The Śrī Yantra (or Śrī Cakra) is a sacred diagram of Tantric Hinduism. Its study stimulated a vast effort of specialists from different fields. In mathematics, its construction sets an elementary and nontrivial problem. In this note, we work out a straightedge and compass method for constructing concurrent models of Śrī Yantras. The question is equivalent to the circle-line-point problem of Apollonious.
Le śrīyantra (ou śrīcakra) est un diagramme sacré dans les traditions hindoues tantriques. Il a fait l’objet de nombreuses études dans différentes disciplines. En mathématiques, sa construction pose un problème élémentaire et non trivial. Dans cette note, on fournit une méthode de construction à la règle et au compas. La question est équivalente à celle d’un problème d’Apollonius qui consiste à trouver un cercle tangent à un cercle donné, à une droite donnée et passant par un point donné.
