Given four collinear points P, Q, R and S list all the line segments determined by them

Given two points P\ a n d\ Q , find how many line segments do they deter-mine. Name the line segments determined by the three collinear points P ,\ Q\ a n d\ Rdot

A,B and C are three collinear points. How many line segment can be determined by them? Name these lines segments?

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

Given p points in a plane, no three of which are collinear q of these Points, which are in the same straight line. Determine the number of (I) straight lines

Mark the following points on a sheet of paper. Tell how many line segments can be obtained in each case: Two points A, B. Three non-collinear points A, B, C. Four points such that no three of them belong to the same line. Any five points so that on three of them are collinear.
