If there are n points in a plane of which m(<n) are collinear, then 1. total number of different straight lines obtained by joining n points is nC2-mC2+1 2. Total number of different triangles formed by joining these n points is nC3-mC3. 3. Number of diagonals in polygon of n sides is nC2-n i.e., [n(n-3)]/2 4. if m parallel lines in a plane are interested by a family of other n parallel lines. Then total number of parallelograms so formed is mC2×nC2. i.e., [mn(m-1)(n-1)]/4 Sir these are IMPORTANT RESULTS ABOUT POINTS Sir please make a video on these points.
