Straight Line
Question
Hello Rabbi. I thought of a good definition for a straight line and also for a line; do you think they are good definitions?
So here it is: A line is something extending between two points. A straight line is the shortest extension between two points.
Answer
Why invent definitions? There are mathematicians who have already done the job.
I don’t know what “extension” means. In any case, the definition of a line is not related to two points in any way.
