Flag of the Maldives — construction sheet
Own work. Geometry and dimensions from the Constitution of the Republic of Maldives — Schedule 3


Composition of national flag: As provided in Article 12 of this Constitution, the national flag of the Republic of Maldives comprises of a green rectangle with a white crescent in the centre, the green rectangle being surrounded by a red border.

Dimensions: The width of the national flag is two-thirds of its length. The width of the red border is one-fourth of the width of the flag. The radii of both curvatures crescent are onethird of the width of the green rectangle. They are drawn from two points on a centre line across the length of the green rectangle, the first point being nine-sixteenth and the second at five-eighths of the length, measured from the side nearer to the staff, joining together to form a crescent. When the flag is hoisted the curvature of the crescent should face out.— extract from Constitution of the Republic of Maldives  — Schedule 3

The last sentence could be considered to be ambiguous because it does not state whether the concave side or the convex side faces out.  Not to worry because Schedule 3 also includes an image (drawing) of the flag. The concave side of the crescent faces towards the fly end of the flag.
