Dialog for Angles

Additional to the usual elements, angles can have different draw sizes. The biggest one will draw the angle ABC through A.

Angles can have Greek letters, if the Java runtime supports this. E.g., alpha can be easily entered as \a. They can be filled. In this case is is probably necessary to draw the angle in the background.

If this icon is deactivated the angle will always be acute, and its value will be in the rangle from 0 to 180.

Fixed angles can be flipped to the other side of AB.

Moreover the ray can be hidden.

For fixed angles, you have an additional "Set Size ..." option, that takes the size from another angle formed by three points ABC. Simply select these three points.
