It is known that plane a is parallel to plane B, and the distance between them is d. if line L is in plane a, there are several lines converging with line L in plane B to form 2D

It is known that plane a is parallel to plane B, and the distance between them is d. if line L is in plane a, there are several lines converging with line L in plane B to form 2D

There are two. Analysis: remember that the straight line in B in the plane is m. if it is a straight line out of plane with the straight line L, then it is easy to know that the distance between the common vertical line segment of the straight line m and l is equal to the distance D of the two parallel planes, which is not a problem. Therefore, the straight line m and the straight line L are not out of plane straight lines, and m and L are not intersecting

If line L is parallel to plane a and line a belongs to plane a, then the relationship between line L and line a

If the line L ‖ plane α and the line a ∈ α, then there are only two relations between the line L and the line A
1) L ∥ a, or, 2) out of plane

In the same plane, a line parallel to a known line L has___ A line passing through a point m outside the line L and parallel to the known line L has_____ Article
