    I am having trouble finding a frame of reference where I can imagine three
    180d angles.  If I recall, Herbert or George also surmised it you example
    might be considered a total of 180d.
    
    From my perspective, if I raise the center point just a hair off the equator
    I would see a triangle.  The center angle close to 180d, and the other two
    close to 0d.  Same if I raise and end point just a hair.
    
    How do I adjust my frame of reference to imagine three 180d angles in your
    above example?
