<strong>Diff\u00e9rence horizontale (\u0394x)<\/strong>, la <strong>Diff\u00e9rence verticale (\u0394y)<\/strong> et le <strong>Milieu du segment<\/strong>.<\/li>\n<\/ol>\n<p>Le r\u00e9sultat est toujours exprim\u00e9 dans l'unit\u00e9 choisie pour x\u2081. Si vous saisissez les coordonn\u00e9es dans des unit\u00e9s diff\u00e9rentes, le calculateur convertit tout en m\u00e8tres en interne, puis reconvertit les r\u00e9sultats dans l'unit\u00e9 de x\u2081\u00a0: une saisie mixte du type \u00ab\u00a0x\u2081 en pieds, y\u2082 en pouces\u00a0\u00bb donne donc toujours un r\u00e9sultat correct.<\/p>\n<h2>Qu'est-ce que la distance entre deux points\u00a0?<\/h2>\n<p>Dans un plan \u00e0 deux dimensions, la distance entre deux points est la longueur du segment de droite qui les relie \u2014 le chemin le plus court possible. \u00c9tant donn\u00e9 \\(P_1 = (x_1, y_1)\\) et \\(P_2 = (x_2, y_2)\\), imaginez un triangle rectangle dont les c\u00f4t\u00e9s de l'angle droit sont le d\u00e9calage horizontal \\(\\Delta x\\) et le d\u00e9calage vertical \\(\\Delta y\\). La formule de la distance applique simplement le th\u00e9or\u00e8me de Pythagore \u00e0 ce triangle \u2014 d'o\u00f9 les trois op\u00e9rations \u00e0 effectuer\u00a0: \u00e9lever au carr\u00e9, additionner, puis prendre la racine carr\u00e9e.<\/p>\n<p>Les r\u00e9sultats interm\u00e9diaires \u0394x et \u0394y sont souvent aussi utiles que la distance elle-m\u00eame. Ils indiquent de combien les points sont \u00e9cart\u00e9s le long de chaque axe et dans quel sens \u2014 exactement ce qu'il faut pour r\u00e9soudre des probl\u00e8mes de pente, de vecteurs ou de d\u00e9placement en physique. La pente de la droite passant par les deux points vaut par exemple \\(\\Delta y \/ \\Delta x\\).<\/p>\n<p>Le calculateur renvoie \u00e9galement le <strong>milieu<\/strong> du segment\u00a0: le point \\(\\left(\\frac{x_1 + x_2}{2}, \\frac{y_1 + y_2}{2}\\right)\\) situ\u00e9 exactement \u00e0 mi-chemin entre les deux points donn\u00e9s. On l'obtient en faisant simplement la moyenne des coordonn\u00e9es \u2014 le m\u00eame principe que celui du <a href=\"https:\/\/wpcalc.com\/fr\/mathematiques\/calculateur-moyenne\/\">calculateur de moyenne<\/a>.<\/p>\n<p>Cette distance est dite <em>euclidienne<\/em>, car elle provient de la g\u00e9om\u00e9trie euclidienne classique. C'est la mesure de r\u00e9f\u00e9rence en g\u00e9om\u00e9trie analytique, pour la navigation sur des cartes planes, en infographie et dans de nombreux algorithmes d'apprentissage automatique qui comparent des vecteurs de caract\u00e9ristiques.<\/p>\n<h2>Limites et conseils pratiques<\/h2>\n<ul>\n<li><strong>En 2D uniquement.<\/strong> Le calculateur travaille dans un plan. Pour des points en trois dimensions \\((x, y, z)\\), il faudrait ajouter un troisi\u00e8me terme au carr\u00e9\u00a0: \\(d = \\sqrt{\\Delta x^2 + \\Delta y^2 + \\Delta z^2}\\).<\/li>\n<li><strong>Distance en ligne droite.<\/strong> Le r\u00e9sultat est la distance directe \u00ab\u00a0\u00e0 vol d'oiseau\u00a0\u00bb, et non un trajet le long de routes ou contournant des obstacles.<\/li>\n<li><strong>M\u00eame syst\u00e8me de coordonn\u00e9es.<\/strong> Les deux points doivent \u00eatre exprim\u00e9s dans le m\u00eame syst\u00e8me de coordonn\u00e9es (par exemple, tous deux issus de la m\u00eame grille cartographique). M\u00e9langer des coordonn\u00e9es d'origines diff\u00e9rentes donne un r\u00e9sultat sans signification.<\/li>\n<li><strong>Attention aux unit\u00e9s.<\/strong> Tous les r\u00e9sultats utilisent l'unit\u00e9 de x\u2081.
