Preliminary study on the three-dimensional geometry of high school mathematics compulsory 2

The first dimensional geometry of this chapter seems to be not much of a link with higher mathematics, applied to the software is also modeling, engineering drawings and so on? It doesn't matter with cryptography ... Copy the concept for the moment.

* The position of two lines in space is: intersecting, parallel, and coplanar lines (different in any one plane).

* The position relationship between the line and the plane is: line A in the plane α, line A and plane α intersect, line A and plane α parallel.

* Plane and plane position relations are: two planes parallel, two planes intersect.

* Simple geometry: prism, Pyramid, bevel, cylinder, cone, round table and ball, three view what is not detailed painting.
