introduction
These days, on a certain forum, there is a topic that has aroused a wide range of repercussions. What is it? That is to say, it has been suggested that there is a Russian numerator who once proposed that parallel lines can intersect. Leaving aside for a moment what the Russians play, how do we Chinese think about this?
Examples from life
This is an indispensable wire in the vast cities and rural areas of the world, and you want to say that it will intersect, which is also possible, but it intersects only when the terminal is used by the user. However, there is absolutely no intersection between two poles, and if a fire is caused, the damage cannot be estimated.
This is a railway, the two tracks can not intersect, why, if they intersect, the train will derail, causing the car to be destroyed and killed, the consequences are very serious.
Do parallel lines intersect in solid geometry?
In layman's terms, stereo geometry is established on the basis of plane geometry, but there is an extra height, that is, the Z axis, since there is no parallel line intersecting in planar geometry, then in the same way, there will be no parallel line intersection in stereo geometry.
What about surfaces?
It seems that there will be no problem of intersection of surfaces, and it may not be two lines that are equal to each other.
Do parallel lines intersect?
This question is still being explored, Chinese most people think that parallel lines will not intersect, otherwise the train will not derail? Isn't the wire short circuit? If someone can prove the example of being able to intersect, let him build a railway on it to try, and if he repairs the intersection of the two rails, he will never give him the project money.
