I know it sounds stupid. But my professor asked us which is the most mathematical flag. As I know most of the flags of the countries are rectangle then what does he mean by most mathematical flag?

    $\begingroup$ Israel has a star of David, which is an interesting graph; Japan has a circle which is the "mathematical perfection" so to speak. The flag of the USA can be used to count things using stars and stripes. And so on and so forth. $\endgroup$ – Asaf Karagila Nov 5 '13 at 11:44

    $\begingroup$ @DanielFischer And since it is the only square flag it exhibits more symmetry than the others. $\endgroup$ – Wintermute Jan 10 '14 at 20:54

The Texas Flag I am developing a math (geometry) exemplar for fourth grade students using the Texas flag. Texas Flag!

The flag code states:

Sec. 3100.001. STATE FLAG. The state flag is the 1839 national flag of the Republic of Texas.

Sec. 3100.002. DESCRIPTION: IN GENERAL.
(a) The state flag is a rectangle that: (1) has a width to length ratio of two to three; and (2) contains: (A) one blue vertical stripe that has a width equal to one-third the length of the flag; (B) two equal horizontal stripes, the upper stripe white, the lower stripe red, each having a length equal to two-thirds the length of the flag; and (C) one white, regular five-pointed star: (i) located in the center of the blue stripe; (ii) oriented so that one point faces upward; and (iii) sized so that the diameter of a circle passing through the five points of the star is equal to three-fourths the width of the blue stripe.
