Flag of Uzbekistan — construction sheet
Own work. Geometry is based on the legal description and diagrams in Law No. 407-XII — 1991-11-18 (amended 2010-12-24).


The state flag of the Republic of Uzbekistan is a rectangular panel of three horizontal stripes of rich blue, white and rich green colors along the entire length of the flag.
The length of the State Flag of the Republic of Uzbekistan is 250 cm, width - 125 cm. The blue, white and green stripes are equal in width. The width of each strip is 40 cm. Along the edges of the white strip, located in the middle of the State Flag of the Republic of Uzbekistan, there are red borders 2.5 cm wide each.
On the upper blue part of the State Flag of the Republic of Uzbekistan on the obverse and reverse sides, at the pole, there is a white crescent and 12 white five-pointed stars next to it.
A white crescent and twelve white five-pointed stars fit into a 75 x 30 cm rectangle along the horizontal axis of the upper blue stripe.
The white crescent is located vertically with its ends from the shaft and fits into a circle with a diameter of 30 cm at a distance of 20 cm from the shaft.
Twelve white five-pointed stars fit into a circle 6 cm in diameter. The distance between the circles is 6 cm. The stars are arranged vertically and horizontally in the following order: three stars in the upper row, four in the middle and five in the bottom. The lower row of stars is located at a distance of 3.5 cm from the lower edge of the crescent.— English translation of Article 4, Law No. 407-XII
The law does not specify the radius, diameter, or centre point of the inner arc of the crescent.  The official diagram that accompanies the legal text appears to have been drawn with an inner arc radius that is equal to the outer arc radius, but it is not explicitly labeled as such.

This Wikimedia construction sheet has been created with the assumption that the outer and inner arc radii are both equal. With that assumption in place; the location of the centre point of the inner arc has been calculated and marked.
