180 degrees. Always 180 degrees. a straight line is also 180 degrees. a circle is 360 degrees. right angle triangle starts with 90 degrees but add up the remaining two you'll still get 180 degrees.

The interior angles add up to 720 degrees The exterior angles add up to 360 degrees

It is 360 degrees because angles around a point add up to 360 degrees

Because angles around any point add up to 360 degrees and the point is the circle's centre.
