The only ways to name a line

Question

I know that you should name a line with two points that lie on the line. (CAPITAL LETTERS)

I know that you can name a line by the single lowercase letter not associated with a point.

Is it acceptable, I wouldn't, to name a line with three collinear points that are all sequential. (similar to naming the line with two points).

I know that you ONLY need two points to name a line.

Answer 1

You could certainly use 3, (usually capital) letters on a straight line to emphasize the point (no pun intended) that the points are collinear.

BTW, in the first line of your question you really mean "two" not "to"!
