Another approach is- 1) Find slop of line AB then draw a line passing through P and having slop equal to AB. 2) check the x-intercepts of AB and line through P to decide left or right.

upload more! i am well aware from the death of a great teacher humblefool, but guys someone needs to continue his legacy... you (most probably his friends or colleagues) have to upload more content and regularly in order to show our respect and honour to him.

@Manikanta The convention is like that . For point above line we take it as left so for that point cross product is positive and so on.

how to define left or right i.e. on what basis are we defining the directions? is it dependent of the Line direction? from POV of observer or from POV of the line itself?

If the cross product is positive then point is right side to the line segment,negative then its left. But in the program its like this if(cross_product>0) return LEFT; else if(cross_product

I assume he meant it is on the left of the line segment, but when he mentioned to the right it is to be from the viewers i.e. our vision perspective

4:40 I have a question BOP is counterclockwise, so that means POB would be clockwise. Then how do you know how to chose BOP instead of POB?

Quoted from a comment: At "A" looking in the direction of "B", where does "P" lie. Makes sense now! Thanks
