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.
How many different lines can be formed by three non-collinear points?
Three
How many straight lines can be formed out of 10 points of which 7 are collinear?
If only 7 are colinear, then the question implies the lines need not go through every point. In that case there is an infinity of lines for each point.
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.
What is it called when two collinear lines meet?
Collinear lines lie on the same straight line passing through the same points and they are coplanular lines when meeting on the same plane.
