https://en.wikipedia.org/wiki/TriangleA triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted . In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane (i.e. a two

Triangles are assumed to be two-dimensional plane figures, unless the context provides otherwise (see Non-planar triangles, below). In rigorous treatments, a triangle is therefore called a 2-simplex (see also Polytope). Elementary facts about triangles were

The triangle inequalitystates that the sum of the lengths of any two sides of a triangle must be greater than or equal to the length of the third side. That sum can equal the length of the third side only in the case of a degenerate...

https://fr.wikipedia.org/wiki/Triangle- Notations
Un triangle est complètement déterminé par la donnée de ses trois sommets et il se note en général en juxtaposant les trois lettres (a priori capitales) qui les désignent. L'ordre de ces lettres importe peu même si l'ordre d'énonciation correspond en général à un parcours dans le sens trig… - Cas particuliers
Un triangle dans lequel au moins deux sommets sont confondus est dit dégénéré (ou parfois en aiguille[réf. nécessaire]). Un triangle platest un triangle dont les sommets sont alignés. Un triangle isocèle est un triangle ayant au moins deux côtés de même longueur. Les deux angles adjacent…
