Karya sendiri. Basic geometry from specification at Myanmar National Portal. Diameter and center point of the star were derived using trigonometry.

1. The model size, measurement and colour et cetera of the Union flag are as follows:

  (a) The model size of the Union flag is rectangular, with 9 feet in length and 6 feet in width;

  (b) The background colours of the Union flag are yellow, green and red. The yellow, green and red colours shall each be equal to one-third of the 6 feet of the width of the Union flag. Therefore, each colour shall be 2 feet;

  (c)

    (i) A large white star with five vertices shall be superimposed on the background of yellow, green and red colours;

    (ii) The upper vertex of the large white star shall be at the mid-point of the length of the Union flag, that is the place at 4 feet and 6 inches and shall point directly upwards;

    (iii) The distance from the top of the star to the boundary of the yellow colour of flag and the distance from the top of two lower vertices of the star in the red colour to the boundary of the red colour of the flag shall be one foot each;

    (iv) The distance between each top of the vertex of the star shall be 2 feet and 7.2 inches equally;

It is assumed that the distance of 2 feet 7.2 inches provided in section 1(c)(iv) is is a redundant approximation. The distance between each "tip" is an irrational number that can be calculated from other parameters. The calculated value is approximately 2 feet 7.19229072 inches.

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

• D: Diameter of an imaginary circle around the star
• A: Distance from the center of the flag to the center of the imaginary circle
