Question

(РУС)Точка М не лежит в плоскости треугольника АВС. Какое взаимное расположение приямих МА и ВС? А прямых ЕF и РК, если точки Е и Р лежат на прямой МА, и точки F и К - на прямой ВС? (УКР)Точка М не лежить у площині трикутника АВС. Яке взаємне розміщення приямих МА і ВС ? А прямих ЕF і РК, якщо точки Е і Р лежать на прямій МА, та точки F і К - на прямій ВС ?

Answer 1

The position of lines MA and VC when point M does not lie in the plane of triangle ABC:

When point M does not lie in the plane of triangle ABC, the lines MA and VC are skew lines. Skew lines are lines that do not intersect and are not parallel. They are lines that exist in different planes and have no common point of intersection.

The position of lines EF and RK when points E and R lie on line MA, and points F and K lie on line VC:

When points E and R lie on line MA, and points F and K lie on line VC, the lines EF and RK are also skew lines. Similar to the previous case, these lines do not intersect and are not parallel. They exist in different planes and have no common point of intersection.
