Question 537716
<font face="Times New Roman" size="+2">


Imagine a convex polygon (any number of sides) large enough for you to walk around.  Extend one of the sides out past the vertex into the area outside of the polygon.  Now stand on the vertex with the extension facing in the direction of the extension.  Turn and walk along the next side until you get to the next vertex, then turn and follow the next side, and so on until you arrive back at the point you started.  You will have turned exactly 360 degrees if you add the number of degrees of angle you turn at each vertex.
