38. Draw three different convex polygons. If you go to a polygon, to turn every corner you turn right (clockwise) or left (left). A left is measured by a positive number of degrees and a right curve with a negative number of degrees. Find the sum of the rotation angle of the polygon you drew. Suppose you start at a point in the direction of one side, walk around the polygon, and end at the summit itself in the same direction as when you started.
