Triangles Isométriques

This lecture introduces the concept of isometric triangles, defined as two triangles that can be transformed into each other through an isometry. It explores the properties of isometric triangles, such as the equality of corresponding sides and angles. Various conditions for determining isometric triangles are discussed, along with proofs involving transformations and symmetry. The lecture also covers the concept of distance between points and how it relates to isometric triangles.
