To solve the problem step by step, we will find the number of different straight lines, triangles, and quadrilaterals that can be formed with `n` points in a plane where no three points are in a straight line except for `m` points that are collinear. ### Step 1: Finding the Number of Different Straight Lines 1. **Understanding the Problem**: - We have `n` points in total. - Out of these, `m` points are collinear (i.e., they lie on the same straight line). - The remaining `n - m` points are not collinear. ...
