Математика, 5 класс Учебник, авторы: Бунимович Евгений Абрамович, Дорофеев Георгий Владимирович, Суворова Светлана Борисовна, Кузнецова Людмила Викторовна, Минаева Светлана Станиславовна, Рослова Лариса Олеговна, издательство Просвещение, Москва, 2023, оранжевого цвета, страница 84, номер 269, Условие

269 Начертите в тетради угол и обозначьте его $AOC$. Проведите луч $OB$ так, чтобы он разделил угол $AOC$ на два угла. Назовите эти углы. Сравните их.

Решение 2. №269 (с. 84)

Сначала необходимо начертить произвольный угол. Обозначим его вершину буквой $O$, а стороны — лучами $OA$ и $OC$. Таким образом, мы получим угол $AOC$.

Далее, из вершины $O$ проведем луч $OB$ так, чтобы он находился внутри угла $AOC$, то есть между лучами $OA$ и $OC$.

Этот луч $OB$ разделил исходный угол $AOC$ на два новых угла. Эти углы называются: угол $AOB$ (или $∠AOB$) и угол $BOC$ (или $∠BOC$).

Для сравнения полученных углов $∠AOB$ и $∠BOC$ нужно рассмотреть их величины. Так как в условии не сказано, как именно должен быть проведен луч $OB$, то возможны три различных случая:

  1. $∠AOB < ∠BOC$. В этом случае угол $AOB$ меньше угла $BOC$. Такое возможно, если луч $OB$ проходит ближе к стороне $OA$.
  2. $∠AOB > ∠BOC$. В этом случае угол $AOB$ больше угла $BOC$. Такое возможно, если луч $OB$ проходит ближе к стороне $OC$.
  3. $∠AOB = ∠BOC$. В этом случае углы $AOB$ и $BOC$ равны. Луч $OB$ при таком расположении является биссектрисой угла $AOC$, так как делит его пополам.

Вне зависимости от того, какой из трех случаев реализуется, всегда выполняется свойство, что сумма двух новых углов равна исходному углу: $∠AOC = ∠AOB + ∠BOC$.

Ответ: Луч $OB$ разделяет угол $AOC$ на два угла: $∠AOB$ и $∠BOC$. В зависимости от положения луча $OB$, угол $∠AOB$ может быть меньше, больше или равен углу $∠BOC$.
