# Class VectorMath

Various vector math utility functions.

### Version

A lot of functions in the Polygon class have been moved to this class the names have changed slightly and everything now consistently assumes a left handed coordinate system now instead of sometimes using a left handed one and sometimes using a right handed one. This is why the 'Left' methods in the Polygon class redirect to methods named 'Right'. The functionality is exactly the same.

Note the difference between segments and lines. Lines are infinitely long but segments have only a finite length.
