angle clockwise or counterclockwise?
I am writing a program that needs to determine the angle between two line segments and whether the angle is clockwise or counterclockwise from the main segment.
How do I determine the direction of the angle from the main segment?
All the coordinates are positive numbers. The segments are of variant sizes.
The solution needs to be an equation since I will have to insert it in some code.

Math isn't exactly my forte. Would you mind explaining how to do a cross product of vectors?
Say I have a(x,y), b(x, y) and c(x, y), how do I do the cross product of ab x cb?
The cross product would be
(bx - ax)*(cy - ay) + (by - ay)*(cx - ax)
- x * y yields a positive number
- y * x yields a negative number
