It requires contractors to use ratios and fractions to complete conversions. They are not copyright. This is the "pure" form of geometric construction: no numbers involved! This construction math self-paced class is intended to develop mathematical skills that can be applied to the construction trade through practice and application. Ou encore, c'est une figure du théorème de Thalès avec trois parallèles au lieu de deux; par rapport au grand triangle ainsi formé, les deux premières parallèles, passent par le premier tiers et le deuxième tiers de chaque côté. Par le théorème de Thalès. �z�0cH��{���xl7�X�`�Y endobj Pour tracer la parallèle à (QB) passant par N : - mettre un côté de l'angle droit de l'équerre sur (QB) - caler la règle contre l'autre côté de l'angle droit de l'équerre - faire glisser l'équerre sur la règle jusqu'à ce que le côté perpendiculaire à la règle passe par N - tracer la droite contenant alors ce côté d'équerre : c'est la parallèle cherchée (en fait, il faut décaler légèrement l'équerre pour que le tracé au crayon puisse passer par N) AM/AC = AN/AQ (théorème de Thalès) b) tracer une demi-droite; il y aura cinq points à y placer à partir de C.
