360 degrees
ENE plus 90 degrees (clockwise) is SSE.
3 quarters clockwise is 270 degrees clockwise or 90 degrees anti(counter)-clocwise
About 161km
140 + k*360 degrees clockwise where k is any integer.
Going clockwise... 210 degrees. Going anti-clockwise... 150 degrees.
360 degree rotation (clockwise or anticlockwise) leaves any figure in exactly the same position as it was at the start. So YOU DO NOTHING.

Yes, if you turn a shape completely around to its original position it will look like its original position because it will be in its original position. For example if i take a trapezoid and turn it 180 degrees it does not look the same as it did before so it does not have rotational symmetry of 180 degrees.

Minus 270 degrees which is equivalent to a quarter anti-clockwise turn, or +90 degrees.
140 + k*360 degrees clockwise where k is any integer.
Going clockwise... 210 degrees. Going anti-clockwise... 150 degrees.
If you turn 180 degrees clockwise or anticlockwise you will be facing south.
rotate it 90 degrees
It has rotational symmetry of order 2 or more.
Because 180 degrees clockwise is the same as 180 degrees counterclockwise.
