Own work. Basic geometry based on description in File:Libyan Flag Construction Ministry of Information and Guidance 1951.jpg.

The exact particulars of the Libyan National Flag prescribed by Article 7 of the Constitution shall be as follows: The red shall be sign red, and the green permanent green. The Crescent shall be on the hoistward side of the star, and the centre of the circle of which the crescent forms a part shall be in the centre of the flag. The star shall be in the open end of the crescent and one point of the star shall point to the centre of the circle. The maximum width of the 270° crescent shall equal 1⁄6 of its outside diameter which is 1⁄4 of the width of the flag. The distance between the tips of the crescent shall equal that between the uppermost and lowermost point of the star measured along a perpendicular forming the hoistward sides of these two points. The perpendicular shall form a tangent to the outside circumference of the crescent at a point equidistant from the top and bottom of the flag.— Libyan Flag Construction Ministry of Information and Guidance 1951

This construction sheet includes four irrational dimensions that have been derived (calculated) from the given dimensions:

A: Diameter of the inner arc of the crescent
B: Distance from the center of the flag to the center of the inner arc of the crescent
C: Diameter of the imaginary circle around the star
D: Distance from the center of the flag to the center of the imaginary circle around the star
