Question

Some points are plotted on a plane such that any three of them are non collineat Each
point is joined with all remaining points by line segments. Find the number of points if the
number of line segments are 10.​

Answer 1

Step-by-step explanation:

There are 10 different points such that no three of them don't lie on straightline. This means if you select any 3points then they won't be collinear. ... Soline segments formed are 6+6+6+6=6*4=24. Because A is joined to 6 points, B is joined to 6 points and so on.
