Similitude is a concept applicable to the testing of engineering models. Alternatively to the direct observation on the prototype, as well as, to the simulation techniques using mathematical models, it is possible to simulate the prototype with a similar model. A model is said to have similitude with the real application if the two share geometric similarity, kinematic similarity and dynamic similarity. If you apply an isometry to the triangle, then the result will be a triangle where the vertices a, b,c can occur clockwise or anticlockwise. Cours les similitudes terminale s specialite dominique frin.
The similarities group s is itself a subgroup of the affine group, so every similarity is an affine transformation.
