I disagree with ausgeoff. With any enclosed shape, if you start from any point and travel along the path of that shape then any number of turns that are required to make that shape will result in a sum of 360° of angular turns to reach the starting point.
A right angle is 90 degrees 4 right angles make a square or rectangle since there is no limit to how long the right angles have to be but the right angles must always form triangles. This creates a problem in a circle since you can't ever overlap the edges so in a circle a right triangle will only cover 3.1416 of the edges or 78.54% which means in reality it's not even 78.54 Degrees per side it's only really 70.686 Degrees per side of the Circle which 70.686x4 Equals only 282.744 Degrees which would only turn you around about 3.1416th of a full 360 degree circle (Also called a square).
By the Way a Square is not really 360 degrees but 400 degrees but we as humans can only measure in circular motion in circles which are 320 degrees, you always turn at the apex or middle so 400+320=720/2=360 Degrees
Turning in a circle in a square Plane (Even if it's not perfectly flat) will always be 360 degrees as a Circle will always be 320 degrees and a rectangle will always be 400 degrees. However you have to remember that when you overlap you always lose a degree per overlap on the inside and this can be seen easily with circles. However people only think they are walking on a circular surface because they fail to realize how to measure a circle and how circles correlate with the shape of the Universe they are moving in and how the Earth is rectangle in shape but appears perfectly circle to us humans as we can't comprehend a rectangular Earth nor can light illuminate it and light always distorts the further you get away from Earth and the Sun itself (Projection of Mercury and Venus (Or Celestial Adam and Eve's Dead Corpse) is the Cause of the Distortion).
