Четырехугольник является ромбом, если его стороны равны, а диагонали не равны и взаимно перпендикулярны. Имеем вершины:А(3;5;4), В(5;0;2), С(1;1;-2) и Д (-1;6;0). Находим длины сторон: АВ = √((Хв-Ха)²+(Ув-Уа)²+(Zв-Zа)²)= √33 ≈ 5.74456, BC = √((Хc-Хв)²+(Ус-Ув)²+(Zс-Zв)²) = √33 ≈ 5.74456, CД = √((Хд-Хс)²+(Уд-Ус)²+(Zд-Zс)²) = √33 ≈ 5.74456, АД = √((Хд-Ха)²+(Уд-Уа)²+(Zд-Zа)²)= √33 ≈ 5.74456.
