Below is 51°.  The arc swings counter-clockwise from the
right side of the x-axis



Below is 51°+360°=411° which is coterminal with 51°,
the arc swings counter-clockwise from the right side
of the x-axis.



Below is 51°-360°=-309° which is coterminal with 51°.
the arc swings clockwise from the right side
of the x-axis.



-------------------------------------------------

Below is 197°.  The arc swings counter-clockwise from the
right side of the x-axis



Below is 197°+360°=557° which is coterminal with 197°,
the arc swings counterclockwise from the right side
of the x-axis.



Below is 197°-360°=-163° which is coterminal with 197°.
the arc swings clockwise from the right side
of the x-axis.
