No, it is not true. Just think of the three vertices of a triangle.
Collinear points
In plane geometry there is exactly one straight line through two points. There can be any number of curved lines.
Yes
False!
In plane geometry, two points determines or defines one unique line.
Yes, if you are talking about Euclidean geometry.
== == Through any two points there is exactly one straight line.
It depends on the context in which the question is asked: whether it is basic geometry, coordinate geometry or vector algebra. If you can draw a single straight line through a set of points they are collinear; if you cannot then they are not.
Yes they do. In geometry, pentacles (stars) have 10 points.
In Euclidian or plane geometry, there can be only one line through two fixed points. Lines cannot actually be drawn; if you see it it is not a geometric line. If the points are on a curved surface as in a geometry that is non-Euclidian, then there can be infinitely many lines connecting two points.
In coordinated geometry the points on a straight line will determine its equation.
In plane Euclidean geometry, only onle line can go through two distinct points.
