+# Документация
+## Общее описание решения
+- Для выполнения решения, к каждой функции в каждом файле,были добавлены комментарии как выполняется функция.
+- После внесения изменений был выполнен:
+  ```bash
+  git add
+- Добавлены комментарии ко всем функциям внесенным изменениям:
+  ```bash
+  git commit -m "Добавлены комментарии ко всем функциям"
+- Создана новая ветка:
+  ```bash
+  git checkout -b lab_2_documentation
+- Изменения были отправлены на удаленный репозиторий:
+  ```bash
+  git push origin lab_2_documentation
+- Отправил pull request
+
+## Описание каждой функции с примерами вызова
+## Условия значений
+- Неотрицательные (иначе выдаётся ошибка ValueError)
+- Значение должно быть числовым (иначе выдаётся ошибка TypeError)
+- Значение должно подаваться (не None)

+  - **Формула**: ```π * r²```
+  - **Описание**: Вычисляет площадь круга по заданному радиусу ```r```.
+  - **Пример вызова**: ```area(5)``` вернёт приблизительно ```78.54```.
+- **Функция** ```perimeter(r)```:
+  - **Формула**: ```2 * π * R```
+  - **Описание**: Вычисляет периметр (длину окружности) круга по заданному радиусу ```r```.
+  - **Пример вызова**: ```perimeter(5)``` вернёт приблизительно ```31.42```.
+
+2. **Файл** ```square.py```
+- **Функция** ```area(a)```:

+- **Функция** ```perimeter(a, b, c)```:
+  - **Формула**: ```a + b + c```
+  - **Описание**: Вычисляет периметр треугольника со сторонами ```a```, ```b``` и ```c```.
+  - **Пример вызова**: ```perimeter(1, 2, 3)``` вернёт ```6```.
+
+4. **Файл** ```rectangle.py```
+- **Функция** ```area(a, b)```:
+  - **Формула**: ```a * b```
+  - **Описание**: Вычисляет площадь прямоугольника со сторонами ```a``` и ```b```.
+  - **Пример вызова**: ```area(4, 5)``` вернёт ```20```.
+- **Функция** ```perimeter(a, b)```:
+  - **Формула**: ```2 * a + 2 * b```
