Yes
It takes exactly 2 distinct points to uniquely define a line, i.e. for any two distinct points, there is a unique line containing them.
== == Through any two points there is exactly one straight line.
A CD, because it exists in our dimension, has three distinct points you can measure therefor it is a cylinder.
In plane geometry there is exactly one straight line through two points. There can be any number of curved lines.
one plane LINE
False!
Collinear points

Unique line assumption. There is exactly one line passing through two distinct points.
No, it is not true. Just think of the three vertices of a triangle.

== == Through any two points there is exactly one straight line.
Infinitely many if the 3 distinct points are collinear. Otherwise just 1.
A line that passes through a circle at two distinct points is called a secant.
No, because Of any three points on a line there exists no more than one that lies between the other two.
In plane geometry there is exactly one straight line through two points. There can be any number of curved lines.
