<br/>In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane (i.e. a two-dimensional Euclidean space). In other words, there is only one plane that contains that triangle, and every triangle is contained in some plane. If the entire geometry is only the Euclidean plane, there is only one plane and all triangles are contained in it; however, in higher-dimensional Euclidean spaces, this is no longer true. 
<br/>(Wikipedia, The Free Encyclopedia, <a href="https://en.wikipedia.org/wiki/Triangle">https://en.wikipedia.org/wiki/Triangle</a>)"""@en, """En géométrie euclidienne, un triangle est une figure plane formée par trois points (appelés sommets) et par les trois segments qui les relient (appelés côtés), délimitant un domaine du plan appelé intérieur. Lorsque les sommets sont distincts deux à deux, en chaque sommet les côtés délimitent un angle intérieur, d'où vient la dénomination de « triangle ». Le triangle est aussi le polygone le plus simple qui délimite une portion du plan et sert ainsi d'élément fondamental pour le découpage et l'approximation de surfaces.
