Ответ учителя по предмету Геометрия
1.
2. Пусть АВ — данный отрезок. Строим две окружности с центрами в точках А и В радиуса АВ. Эти окружности пересекаются в двух точках М1 и М2. Отрезки AM1, АМ2, BM1, ВМ2 равны друг другу как радиусы этих окружностей. Проводим прямую М1М2. Она является искомым серединным перпендикуляром к отрезку АВ. Точки М1 и М2 равноудалены от концов отрезка АВ, и поэтому они лежат на серединном перпендикуляре к этому отрезку. Прямая М1М2 серединный перпендикуляр к отрезку АВ
