Прямые a и b расположены соответственно в параллельных плоскостях альфа и бетта. Верно ли,что эти прямые не имеют общих точек?(ответ обоснуйте)

Ответы

Автор ответа: KuOV

Предположим, что прямые а и b имеют общую точку. Тогда и плоскости α и β имеют общую точку, а, значит, пересекаются.
Но по условию плоскости α и β параллельны. Противоречие.
Значит, прямые а и b не имеют общих точек.
