*1
The angle and supplementary angle is always displayed as degrees.
*2
When two vectors are selected, the angle that is no the angle formed mathematically by
the two vectors. It merely indicates the simple angle that would be formed if the vectors
were two lines.
*3
The circle itself can be locked.
