Definition let ABC and D be four points is in a plane such that : (i)no three of them are collinear (ii) the line segments ABBCCD and DA do not intersect except at their and points.

Definition let ABC and D be four points in a plane that : ( i ) not three of them are collinear and (ii)the line segments ABBCCD and DA do not intersect except at the their endpoints.

Take four distinct points, A,B,C and D no three of which are collinear. Name the line segments.

Take four distinct point A,B ,C and D , out of which three points are collinear Name the line segments.

There are 8 points in a plane, no three of them are collinear .The number of triangles that can be formed is:

There are 18 points in a plane such that no three of them are in the same line except five points which are collinear. The number of triangles formed by these points, is

The number of lines that can be formed from 12 points is a plane of which no three of them are collinear except 6 points lie on a a line is

In a plane there are 8 points , no three of which are collinear .How many lines do the points determine ?

There are 21 points in a plane no three of which are collinear . The number of triangle by joining them is

Given four points A, B, C, D such that three points ABC are collinear. By joining these points in order to get a closed figure, we get :-

There are 10 points on a plane of which no three points are collinear. If lines are formed joining these points, find the maximum points of intersection of these lines.
