Find the mathematical concept:: 1. How to deduce the parallelism of line and plane and then the parallelism of plane? On the contrary, how to launch it? Specific point
Prove that the straight line is parallel to the plane: if the straight line A is parallel to the straight line B and A belongs to the plane M, then B is parallel to the plane M..

Face-to-face parallelism: If line A is parallel to line B, A belongs to plane M and B belongs to plane N, then plane M is parallel to plane N..

on the contrary

The surfaces are parallel, so that there is no intersection between surface A and surface B;

So any straight line on the A plane does not intersect with the B plane.

A straight line and a plane are parallel because they have no intersection.
