By definition, the word "collinear" means that the points lie in a LINE. The precise manner of line you are talking about depends upon the geometric frame of reference you are using. For example, in Euclidean geometry a line defined by two points is usually taken to be "straight" like the intersection of two planes; but in Global geometry such as the reality of the Earth's surface, a line defined by two points is curved. If you fly from New York to Tokyo, your line of flight is nearly a semicircle; we do not have the technology to travel "straight" from New York to Tokyo through the Earth's core.

How to find out if two sets of points are collinear need help for geometry?
To determine if two sets of points are collinear, you can calculate the slopes of the lines formed by connecting the points in each set. If the slopes are equal, then the points are collinear. Another method is to calculate the area of the triangle formed by the three points in each set. If the area is zero, then the points are collinear. Lastly, you can use the determinant of a matrix method to check if the points lie on the same line.
Are any two points collinear?
No. points are collinear only when they are on the same line
Is it true that two points are always collinear?
Yes, two points are always collinear. You can draw a line through any two points.
What does it mean for two points to be collinear?
"Collinear" means "on the same straight line".Two points are always collinear, because you can always draw a straight linebetween any two points. Three points may or may not be collinear.
What two points are collinear?
Any two points are always collinear, since you can draw a straight line passing through any two points.
