自己的作品. Geometry and dimensions obtained from:
Note: The text in the executive order does not provide the location for the centre of the sun, but the drawing provides enough information to calculate it. Note: The government created another specification drawing in 1955; some of the listed dimensions appear to conflict with the 1936 executive order. It is assumed that the 1936 executive order takes precedence over the 1955 drawing. |

Notes
units
For the purpose of these notes, a unit corresponds to the units used in this construction sheet. One unit is 1/90 the width of the flag or 1/180 the length of the flag.
the sun
- Diameter of the central disk: D = 90/5 = 18 units.
- Length of major rays: R = (5/9) × D = 10 units. Distance between two opposite tips is R+D+R = 10+18+10=38 units.
- Length of minor rays: r = (4/5) × R = 8 units. Distance between two opposite minor tips is r+D+r = 8+18+8=34 units.
- Distance from left edge of flag to left most ray on sun is D/2 = 9 units as shown on the 1936 drawing. Therefore distance from left edge of flag to sun center is D/2 + R + D/2 = 28 units.
- It is apparent that the designers of the flag wanted the rays of the sun to appear as though they were clipped by two squares (or a square and a diamond... or an 8/2 regular star polygon). However, if the flag is drawn to spec, and one superimposes a square by connecting the tips of four opposite major rays, then the minor rays will protrude 0.0519779424 units outside of the square. This is about 0.06% of the width the flag and not generally noticeable to the naked eye. This construction sheet has a pair of red dashed squares connecting the major rays and a set of green dashed lines connecting the minor rays. It is necessary to zoom in to a high magnification level to see that these are actually distinct lines.
the stars
- The three stars are all the same size. They are not 5/2 regular star polygons (pentagrams) and therefore they must be drawn using all 10 points.
- Inner diameter of each star: (2/9) × D = 4 units
- Outer diameter of each star: (5/9) × D = 10 units.
- Each star is positioned such that one point is directed to the closest vertex of the white triangle.
- Distance between each triangle vertex and the tip of the closest star: D/2 = 9. Therefore the distance from triangle vertex to star center is 9 + (10/2) = 14 units.
