266 С помощью кальки найдите на рисунке 5.5 угол, равный углу $A$.

5.5

Решение 2. №266 (с. 84)

Чтобы найти угол, равный углу А, необходимо выполнить сравнение углов с помощью кальки (полупрозрачной бумаги).

  1. Шаг 1: Копирование угла А

    Положите лист кальки на рисунок так, чтобы он покрывал угол А. С помощью карандаша аккуратно перенесите на кальку вершину угла и два луча, образующие его стороны. На кальке получится точная копия угла А.

  2. Шаг 2: Сравнение скопированного угла с другими углами

    Перемещая кальку, последовательно прикладывайте скопированный угол А к каждому из углов на рисунке 5.5 (B, C, D, K, M, N). При наложении необходимо совмещать вершину скопированного угла с вершиной проверяемого угла, а одну из его сторон — с одной из сторон проверяемого угла.

  3. Шаг 3: Анализ результатов сравнения

    Наблюдайте за положением второй стороны скопированного угла относительно второй стороны проверяемого угла:

    • Углы B и C являются тупыми (больше $90^\circ$), в то время как угол А — острый (меньше $90^\circ$). Следовательно, они не могут быть равны углу А.
    • При наложении на угол D вторая сторона скопированного угла А окажется внутри угла D. Это значит, что $\angle D > \angle A$.
    • При наложении на угол K вторая сторона угла K окажется внутри скопированного угла А. Это значит, что $\angle K < \angle A$.
    • При наложении на угол N вторая сторона скопированного угла А окажется внутри угла N. Это значит, что $\angle N > \angle A$.
    • При наложении на угол M вершина и обе стороны скопированного угла А полностью совпадут с вершиной и сторонами угла M. Это значит, что $\angle M = \angle A$.

Таким образом, единственный угол на рисунке, равный углу А, это угол M.

Ответ: Угол M.
