About 25 years ago, when I was studying mathematics at university, in the projective geometry class.
Professor had told us that in the projective geometry parallel lines can meet only at one point
That's when you look at the line vertically
It's like looking at the road in front of you
After completing the course, I had this question in mind
If you look at the lines horizontally as in the picture below, then there are 2 points?
It's like being on the side of the road
Is not that a contradiction, since in the poetic geometry parallel lines can only meet at one point?
Since then I have not had the opportunity to ask someone about it.
Now I wonder if anyone can answer me.
