Without wishing to overcomplicate matters, one could simply define a straight line as:
"the shortest distance between two given points".
I would claim that a straight line is slightly bend as we define straight from the horizon.
a straight line passing from side to side through the center
a line with two arrows on the end.
A minimum of two points is required to draw a straight line. Any two distinct points can be connected by a straight line, and this line will extend infinitely in both directions. Additional points can lie on the same line, but only two are necessary to define the line's direction and position.
Linear functions can be represented by a straight line in space. One way to define a straight line uniquely is to use its slope (or direction vector) and any one point on the line.

In a Euclidean plane any two distinct points uniquely define a straight line.

Only two are necessary to define a line. But infinitely many are required to DRAW it.

It would not have sides because it would be a straight line. A straight angle is 180 degrees. Anything above that is a "Reflex"
It is the shortest distance between two points.
Yes it can, but it would not then be a straight line but an angle.
it would be 180 A perfectly straight line would be an example - like the edge of a ruler. Or a plumb line.
