Диагонали в квадрате взаимно перпендикулярны и равны, следовательно (пусть будет квадрат ABCD, диагонали AC и BD,точка пересечения диагоналей O) AC=BD=6 см. Угол AOD=90 градусов.AO=OD=3 см. По теореме Пифагора AD=Корень из суммы квадратов AO,OD. AD=корень из(3 в квадрате + 3 в квадрате). AD=Корень из 18.
